Diagnosis: ventricular. Ventricular extrasystole, what is it? Treatment and consequences

Ventricular extrasystoles (VES) are extraordinary contractions of the heart that occur under the influence of premature impulses that originate from the intraventricular conduction system.

Under the influence of an impulse generated in the trunk of the His bundle, its branches, branching branches or Purkinje fibers, the myocardium of one of the ventricles contracts, and then the second ventricle without previous contraction of the atria. This explains the main electrocardiographic signs of PVCs: premature dilated and deformed ventricular complex and the absence of a normal P wave preceding it, indicating atrial contraction.

What it is?

Ventricular extrasystole is one of the types of arrhythmias, which are premature, out-of-order contractions of the ventricles. Ventricular extrasystole is characterized by a feeling of disturbances in the functioning of the heart in the form of failures, weakness, dizziness, anginal pain and lack of air.

This type of arrhythmia is established after listening to the heart, electrocardiogram and Holter monitoring. And to treat extraordinary contraction of the ventricles, sedatives, beta-blockers and antiarrhythmic drugs are used.

Causes

The reasons for ventricular extrasystole appear in heart disease:

• inflammatory nature (myocarditis, endocarditis, intoxication);
• myocardial ischemia (foci of cardiosclerosis, acute infarction);
• metabolic-dystrophic changes in the muscle and conduction system (impaired potassium-sodium electrolyte ratio in myocytes and intercellular space);
• a sharp depletion of the energy supply of cells caused by malnutrition, lack of oxygen in acute and chronic heart failure, and decompensated defects.

Ventricular extrasystoles may appear in people with a healthy cardiovascular system due to:

• irritation of the vagus nerve (due to overeating, insomnia, mental work);
• increased tone of the sympathetic nerve (smoking, physical work, stress, hard work).

If there are two sources of impulse formation in the heart, then the main one is the one that is capable of a higher frequency. Therefore, normal sinus rhythm is most often maintained. But extrasystoles can also occur against the background of atrial fibrillation.

Classification

Not all specialists use the existing classification of ventricular extrasystole according to Laun and Wolf. She offers five degrees of extrasystole during myocardial infarction according to the risk of developing fibrillation:

• degree 1 - monomorphic extraordinary contractions are recorded (no more than 30 per hour of observation);
• degree 2 - more frequent, from one focus (over 30 per hour);
• degree 3 - polytopic extrasystole;
• degree 4 - subdivided depending on the ECG pattern of the rhythm (“a” - paired and “b” - volley);
• degree 5 - the most dangerous type “R on T” in a prognostic sense is registered, which means that the extrasystole “climbed” onto the previous normal contraction and is capable of disrupting the rhythm.

In addition, a “zero” degree was allocated for patients without extrasystole.

M. Ryan's proposals for gradation (classes) supplemented the B. Lown - M. Wolf classification for patients without myocardial infarction. In them, “gradation 1”, “gradation 2” and “gradation 3” completely coincide with Launov’s interpretation.

The rest have been changed:

• “gradation 4” - considered in the form of paired extrasystoles in monomorphic and polymorphic versions;
• “gradation 5” includes ventricular tachycardia.

Symptoms

Single ventricular premature contractions are recorded in half of healthy young people during monitoring for 24 hours (Holter ECG monitoring). They do not affect your well-being. Symptoms of ventricular extrasystole appear when premature contractions begin to have a noticeable effect on the normal rhythm of the heart.

Ventricular extrasystole without concomitant heart diseases is very poorly tolerated by the patient. This condition usually develops against the background of bradycardia (slow pulse) and is characterized by the following clinical symptoms:

• a feeling of cardiac arrest, followed by a whole series of beats;
• from time to time, separate strong blows are felt in the chest;
• extrasystole may also occur after eating;
• a feeling of arrhythmia occurs in a calm position (during rest, sleep or after an emotional outburst);
• During physical activity, the disturbance practically does not appear.

Ventricular extrasystoles against the background of organic heart diseases, as a rule, are multiple in nature, but for the patient they are asymptomatic. They develop with physical activity and go away while lying down. Typically, this type of arrhythmia develops against the background of tachycardia.

Many women during pregnancy experience tachycardia and pain in the left side of the chest. The development of PVCs in an expectant mother is not uncommon. This is explained by the fact that the circulatory system and the heart have a double burden. In addition, one should take into account the physiological changes in hormonal levels, which affect the rhythm of impulses. Such extrasystole is not malignant and can be easily treated after childbirth.

Diagnostic methods

Diagnosis of the disease is carried out by two main methods, which include 24-hour ECG and Holter ECG monitoring.

1. An electrocardiogram records all unscheduled contractions of the ventricle, allowing the frequency and sequence of the heart rhythm to be determined.
2. The bicycle ergometry method makes it possible to identify the dependence of the manifestations of gallbladder extrasystoles on the load received, as well as to classify the disease, which greatly facilitates the development of a treatment program.
3. Polycardography, TEE, sphygmography and other methods can also be used as diagnostic methods.

Extrasystole cannot always be detected on an ECG. This is due to the fact that this study is carried out quite quickly (about 5 minutes), and single extrasystoles may simply not be captured on film. In this case, other types of diagnostics are used. One of the techniques is Holter monitoring. It is carried out during the day, in the patient’s usual physical activity, after which the doctor determines whether any heart rhythm disturbances have occurred during this time and how dangerous they are to the patient’s life.

Treatment of ventricular extrasystole

For benign ventricular extrasystole, which is well tolerated by the patient, drug treatment is not carried out. It is recommended to give up bad habits, modify risk factors, and possibly take Corvalol.

In case of frequent PVCs, pronounced clinical manifestations, or malignant course, antiarrhythmic drugs are prescribed:

1. Propafenone is a class I antiarrhythmic, used when the course is benign. Contraindicated in cases of LV aneurysm and severe heart failure.
2. Bisoprolol is an adrenergic blocker that prevents ventricular fibrillation and regulates heart rate. Contraindicated in patients with bronchial asthma.
3. Cordarone is the drug of choice for malignant and prognostically unfavorable PVCs. Reduces cardiac mortality rates.

Surgical treatment is carried out for frequent ventricular extrasystoles, which are difficult to treat with drugs. An electrophysiological study is performed to determine the exact location of the lesion and its radiofrequency ablation.

Lifestyle with ventricular extrasystole

With ventricular extrasystole, especially caused by other heart diseases, you need to rest more, spend more time in the fresh air, observe a work-rest schedule, eat right, avoid drinking coffee, alcohol, and reduce or eliminate smoking.

Patients with a benign type of ventricular extrasystole do not need to limit physical activity. With the malignant type, significant stress and psycho-emotional situations that can lead to the development of an attack should be limited.

Traditional methods

If the extrasystole is not life-threatening and is not accompanied by hemodynamic disturbances, you can try to defeat the disease on your own. For example, when taking diuretics, potassium and magnesium are removed from the patient’s body. In this case, it is recommended to eat foods containing these minerals (but only in the absence of kidney disease) - dried apricots, raisins, potatoes, bananas, pumpkin, chocolate.

Also, to treat extrasystole, you can use an infusion of medicinal herbs. It has cardiotonic, antiarrhythmic, sedative and mild sedative effects. It should be taken one tablespoon 3-4 times a day. For this you will need hawthorn flowers, lemon balm, motherwort, heather and hop cones. They need to be mixed in the following proportions:

• 5 parts each of lemon balm and motherwort;
• 4 parts heather;
• 3 parts hawthorn;
• 2 parts hops.

Important! Before starting treatment with folk remedies, you should consult your doctor, because many herbs can cause allergic reactions.

Consequences

Ventricular extrasystole type 1, according to the classification given above in the article, is not life-threatening and usually does not cause any complications. With type 2 ventricular extrasystole, complications may develop, but the risk is relatively low.

If the patient has polymorphic extrasystoles, paired extrasystoles, unstable paroxysmal tachycardia or early group extrasystoles, there is a high risk of life-threatening consequences:

1. Stable ventricular tachycardia is characterized by prolonged (more than half a minute) attacks of group ventricular extrasystoles. This, in turn, provokes the consequences shown later in this table.
2. Ventricular flutter Contraction of the ventricles at a rate of 220 to 300 beats per minute.
3. Ventricular fibrillation (flickering) Chaotic contractions of the ventricles, the frequency of which reaches 450 beats per minute. The fibrillating ventricles are unable to pump blood, so the patient usually loses consciousness due to lack of oxygen to the brain. This condition, if left untreated, can cause death.
4. Asystole (cardiac arrest) May occur against the background of an attack of ventricular arrhythmia or suddenly. Often, asystole inevitably leads to death, since doctors are not always able to perform resuscitation within a few minutes after cardiac arrest.

To avoid life-threatening consequences, do not delay starting treatment if you are diagnosed with ventricular extrasystole.

Forecast

With a benign course and the absence of an underlying cardiac disease, the prognosis is favorable.

With a potentially malignant type and in the presence of organic damage to the heart, the prognosis is relatively unfavorable and is determined not only by the characteristics of ventricular extrasystoles according to ECG monitoring (frequent, average, paired, group), but also by the nature of the underlying disease and the stage of heart failure, in the later stages of which the prognosis is not favorable . With a malignant course, the prognosis is unfavorable due to the very high risk of sudden cardiac death.

Taking antiarrhythmic drugs in combination with beta blockers can improve the prognosis, since the combination of these drugs not only improves the quality of life, but also significantly reduces the risk of complications and death.

Prevention of the disease

• maintaining a more active and mobile lifestyle;
• giving up bad habits, including smoking, excessive consumption of alcohol and strong coffee;
• regular medical examinations.

Detection of a disease can occur even during a routine preventive examination; for this reason, a health check in a medical institution is a mandatory event for everyone.

Ventricular extrasystole (VC) is a type. Manifests itself in the form of extraordinary and premature contractions of the heart ventricles. Patients feel dizziness, general weakness, sometimes pain in the heart and lack of oxygen. To identify a violation, you need to undergo a comprehensive examination. In most situations, treatment is carried out with medications. In rare cases it can. Ventricular extrasystole in children is diagnosed only in 5% of cases, but as they grow older, the likelihood of a disorder increases to 50%. Therefore, PVCs are considered a pathology for people over 45 years of age. The danger lies in the possibility of sudden cardiac arrest. PVCs are also called ventricular extrasystole and ventricular arrhythmia. ICD 10 (International Classification of Diseases) has assigned this disease ICD code I49.3.

Ventricular extrasystole requires treatment.

Causes

Understanding what it is and what consequences it can lead to, it is necessary to be able to recognize the symptoms of ventricular extrasystole and be aware of the potential causes of the disorder. Changes in ventricular rhythm are not always perceived as a pathological disorder. Ventricular extrasystole is considered a deviation that is safe for health and life. There is a certain norm per day at which PVCs are classified as a harmless change:

• from 700 to 950 additional impulses can be in people who do not suffer from disorders of the cardiovascular system, and this is the norm;
• 960 – 1200 pulses are considered normal if the patient has been diagnosed with polymorphic ventricular extrasystole, and there is no threat to life or health;
• 1200 extrasystoles or more require the intervention of specialists, since this is already a serious deviation that can lead to tachycardia and other dangerous consequences.

About 75% of the total population falls into the first two groups. This is not a rare disease that should not be perceived as a dangerous pathology. But if the extrasystole occurs in parallel with other pronounced disorders, it is better to consult a cardiologist, undergo a comprehensive examination and carry out treatment, if necessary. Heart rhythm disturbances are distinguished by the type of ventricular extrasystole, depending on the causes of occurrence. This can be functional, idiopathic ventricular extrasystole or cardiac.

Cardiac causes include:

• chronic heart failure;
• arterial hypertension;
• myocarditis;
• pericarditis;
• hypertrophic cardiomyopathy;
• dilated cardiomyopathy, etc.

There are also functional causes or a functional type of PVCs that are not associated with diseases of the cardiovascular system. These factors include:

• and tobacco products;
• sleep disorders;
• regular use of anesthetic drugs;
• disturbances of micro metabolic processes in the body;
• exceeding prescribed dosages of medications;
• abuse of narcotic and psychotropic drugs;
• osteochondrosis;
• infectious lesions;
• severe stress, anxiety and emotional turmoil, etc.

Ventricular extrasystole has many causes, but the disorder does not always manifest itself against the background of obvious provoking factors. There are cases when no specific causes have been identified for ventricular extrasystole. The arrhythmia was provoked by unknown factors against the background of the patient’s excellent health condition. Therefore, everyone, even a healthy person, should have an attending physician in the cardiology department, to whom he can periodically come for preventive diagnostics.

Signs

Quite often, ventricular extrasystole is detected only on an ECG, and obvious signs of the disorder are absent or weakly manifested, which is why the patient simply does not pay attention to them. Less often, symptoms become more pronounced. Then PVCs can be detected based on the following manifestations:

• there is a feeling of disruption in the functioning of the heart muscle;
• the heart seems to freeze or push in an increased mode;
• the person gets tired quickly and becomes very irritable;
• headaches and dizziness occur periodically;
• there is a lack of oxygen, the patient seems to be suffocating;
• there is pain in the heart and severe weakness of the whole body;
• In rare cases, with this disorder, the patient may faint.

During examinations, doctors observe characteristic pulsations of the veins in the neck. The pulsation can be arrhythmic, with long pauses and extraordinary impulses. But you need to make sure that the diagnosis is correct, for which instrumental diagnostic methods are used.

Gradation of PVCs

Although adults are more likely to have ventricular arrhythmia, children should also be checked to prevent possible complications. For a child and an adult, the same gradation of ventricular extrasystole is used. In total, there are several stages of PVC, which determine whether treatment is necessary to eliminate it. The first stage (or 0) indicates the absence of extrasystole. The condition is normal and does not pose any danger. That’s why they start from the first class.

1. The first class (1) indicates arrhythmia in the amount of up to 30 extra impulses per hour. This is a common ventricular extrasystole. It is a normal health condition, does not pose a threat and does not require treatment.
2. Second class (2). This is a single ventricular extrasystole, manifested in the form of more than 30 extra impulses per hour. It’s worth paying attention to and slightly adjusting your lifestyle. But it does not pose a serious threat.
3. Third grade (3). Polymorphic extrasystoles, having different shapes during one ECG. If there are multiple episodes of ventricular arrhythmia, special treatment will be required.
4. The fourth class (4a) refers to paired ventricular extrasystoles following each other.
5. The fourth class (4c) is called volley extrasystoles, manifested in the form of 3 - 5 extrasystoles one after another.
6. Fifth grade (5). This is already ventricular tachycardia, requiring mandatory surgical intervention.

The last three classes of PVCs can lead to dangerous and serious consequences for human health, including fibrillation and tachycardia. The result of such complications is sudden cardiac arrest with all the ensuing consequences, including the death of a person. How dangerous a PVC is depends directly on its type. To determine the nature of the lesion and the number of unnecessary contractions (impulses), it is necessary to conduct a comprehensive examination of the patient in the cardiology department. It is dangerous to ignore the manifestations of frequent ventricular extrasystole, so at the first sign or suspicion of abnormal heart function, seek help.

Treatment methods

For ventricular extrasystole, treatment is selected individually. It is difficult to choose tactics and schemes, since this is influenced by a number of factors. The primary factor for choosing treatment methods is the severity of PVCs. Sometimes the patient may not be given any treatment at all. All recommendations boil down to normalizing a healthy lifestyle and eliminating potentially harmful provoking factors. Only in 25% of all cases of PVC is there a likelihood of developing any complications that require a course of therapy. The majority of cases of ventricular arrhythmia fall under normal conditions, and therefore taking medications or performing other procedures can only cause harm. If symptoms of rhythm disturbance occur periodically or are isolated, you need to try to get rid of the provoking factors. The basis of therapy is maintaining optimal electrolyte balance and pressure. All patients should eat properly and saturate the body with potassium.

Treatment may be:

• medicinal;
• radio frequency;
• implantation

The doctor determines how to treat the patient and what methods are best to use. Let's talk about each type of therapy separately.

Drug therapy

Doctors will first try to treat the disorder with medication. PVC interacts well with many medications. Therefore, the selected treatment regimen for the patient may include:

1. Sodium channel blockers. These are several different classes of drugs, including Quinidine, Mexiletine and Flecainide. They have their own strengths and weaknesses. The specific class and representative of this segment is selected by the attending physician individually, taking into account the patient’s clinical picture. Recent studies have shown that taking these blockers is dangerous for people who have experienced ventricular extrasystole after a heart attack. This is due to an increase in mortality after the use of drugs;
2. Beta blockers. This category of drugs is relevant for patients in whom ventricular extrasystole was caused by organic heart disease.
3. Calcium channel blockers. They are prescribed in rare cases, since recent observations have shown the absence of a significant effect of these drugs on the condition of patients.

Specific medications, course duration and number of uses are determined by the attending physician, based on the patient’s collected medical history and the results of a comprehensive examination.

This is a method of surgical intervention, which is relevant in the absence of the effectiveness of medications, the individual characteristics of the patient’s body, or the urgent need to influence the current condition. But RFA has a number of contraindications, which is why not every patient is allowed to undergo such an operation. This is a minimally invasive method based on the introduction of a special catheter with an electrode through the femoral artery, which destroys areas that lead to the formation of unnecessary impulses of the heart muscle. After surgery, patients recover quickly. Complications are rare, but their likelihood is always present.

Implantation

Implants can be installed in a patient in the rarest situations. This is relevant when detecting malignant extrasystole of the ventricles of the heart muscle, when there is a high probability of sudden death due to changes in the functioning of the heart. A special implant normalizes impulses and contractions. But it makes serious changes to a person’s usual way of life. Prognosis for life with PVCs can only be made based on the form of cardiac arrhythmia and the presence of organic heart pathologies. Functional ventricular extrasystole is safe for human life and health. But it’s worth normalizing your lifestyle and giving up bad habits.

Adults and children are recommended to undergo periodic cardiovascular examinations. An ECG is a simple, quick, but informative diagnostic procedure. If you conduct an electrocardiogram once a year, you will be able to regularly observe changes in the functioning of the heart muscle, note disturbances and respond to them in a timely manner. Preventive examinations are especially relevant for patients with a genetic predisposition to heart disease. Therefore, it is important for parents to check the health status of their child, as well as monitor the functioning of the heart muscle themselves. The earlier negative changes can be detected, the higher the likelihood of quickly eliminating them with minimal damage to health and the family budget.

One of the common types of arrhythmic pathology is ventricular extrasystoles, when impulses are formed not in the sinus node, but in various (ectopic) parts of the conduction system of the right or left ventricle.

This leads to extraordinary contractions occurring throughout the entire heart or its individual parts, in this case the ventricles.

When ventricular extrasystoles occur, the heart is prematurely excited, it beats strongly or, conversely, freezes. Cardiac output decreases, coronary and cerebral blood flow slows down. This may result in angina, atrial fibrillation, or death.

Extrasystoles can have different natures and symptoms, but the most dangerous are ventricular ones.

Depending on the time of formation, nature and number of extrasystoles, they are divided into 5 classes:

The most typical occurrence of pathology is in adulthood; usually extrasystoles are found in 70% of patients who have heart complaints. The disease is a sign that structural and functional changes are present in the myocardium, but often heart damage is not detected using standard instrumental methods.

If right ventricular extrasystole or left ventricular extrasystole occurs against the background of another cardiac pathology, patients should first of all resort to the prevention of the underlying disease and lead a healthy lifestyle, this will not allow the arrhythmias to progress.

Content

One of the most common heart rhythm disturbances (HRA) is extrasystole, i.e. extraordinary (“intercalated”) contraction of the ventricular myocardium. According to statistics, more than 40% of people over the age of 40 suffer from such cardiac pathology. In addition, during instrumental studies of the heart and ECG registration, ventricular extrasystole is detected in healthy individuals under 30 years of age in 10-15% of cases and is considered a variant of the physiological norm.

What is ventricular extrasystole

The phenomenon of ventricular extrasystole (VES) is an extraordinary single contraction of the myocardium that occurs under the influence of premature electrical impulses that emanate from the wall of the chambers of the right or left ventricle, as well as the nerve fibers of the conduction system of the heart (the His bundle, Purkinje fibers). As a rule, extrasystoles that occur during PVCs negatively affect only the ventricular rhythm, without disrupting the functioning of the upper parts of the heart.

Classification

The standard Lown classification was created based on the results of 24-hour Holter ECG monitoring. It distinguishes 6 classes of ventricular extrasystole:

1. 0 class. On the ECG there is no frequent ventricular extrasystole, the patient does not experience any changes in heart function or morphological changes.
2. 1 class. During one hour of observation, less than 25-30 single monomorphic (monotopic, identical) ventricular pathological contractions were recorded.
3. 2nd grade. During the hour of the study, more than 30 single monomorphic or 10-15 paired extrasystoles were recorded.
4. 3rd grade. During the first 15 minutes, at least 10 paired, polymorphic (polytopic, heterogeneous) extrasystoles are recorded. Often this class is combined with atrial fibrillation.
5. 4a grade. Over the course of an hour, monomorphic paired ventricular extrasystoles were recorded;
6. 4b grade. During the entire duration of the study, polymorphic paired ventricular extraordinary contractions are recorded.
7. 5th grade. Group or salvo (3-5 in a row for 20-30 minutes) polymorphic contractions were recorded.

Frequent ventricular extrasystole of class 1 does not manifest itself symptomatically and is not accompanied by serious pathological changes in hemodynamics, therefore it is considered a variant of the physiological (functional) norm. Extraordinary contractions of classes 2-5 are combined with a high risk of developing atrial fibrillation, sudden cardiac arrest and death. According to the clinical classification of ventricular arrhythmias (according to Mayerburg), there are:

1. Extrasystoles of a benign, functional course. They are characterized by the absence of clear clinical symptoms of organic myocardial pathology and any objective signs of left ventricular dysfunction. The function of the ventricular node is preserved and the risk of cardiac arrest is minimal.
2. Ventricular arrhythmias have a potentially malignant course. They are characterized by the presence of extraordinary contractions against the background of morphological lesions of the heart muscle, a decrease in cardiac output by 20-30%. They are accompanied by a high risk of sudden cardiac arrest and are characterized by a gradation towards a malignant course.
3. Arrhythmias of malignant course. Characterized by the presence of ventricular extraordinary contractions against the background of severe organic myocardial damage, they are accompanied by a maximum risk of sudden cardiac arrest.

Reasons for ventricular extrasystole

The appearance of extraordinary contractions of the ventricles is caused by organic pathologies of the myocardium and the use of medications. In addition, extrasystole is a frequent complication of other systemic lesions: endocrine diseases, malignant tumors. Some of the most common causes of PVCs are:

• ischemic disease;
• cardiosclerosis;
• myocardial infarction;
• myocarditis;
• arterial hypertension;
• pulmonary heart;
• chronic heart failure;
• mitral valve prolapse;
• uncontrolled use of M-anticholinergics, sympathomimetics, diuretics, cardiac glycosides, etc.

Functional or idiopathic ventricular arrhythmia is associated with smoking, stress, and consumption of large quantities of caffeinated drinks and alcohol, which lead to increased activity of the autonomic nervous system. Extrasystole often occurs in patients who suffer from cervical osteochondrosis.

Symptoms of frequent ventricular extrasystole

Single premature myocardial contractions are recorded in many healthy young people during monitoring of heart function throughout the day (Holter ECG monitoring). They do not have a negative impact on well-being; a person does not notice their presence in any way. Symptoms of extraordinary contractions appear when hemodynamics are disrupted due to extrasystoles.

Ventricular arrhythmia without morphological lesions of the myocardium is difficult for the patient to tolerate; attacks of suffocation and panic occur. This condition usually develops against the background of bradycardia and is characterized by the following clinical manifestations:

• sensation of sudden cardiac arrest;
• isolated strong beats in the chest;
• worsening after eating;
• disruption of heart function in the morning after waking up, an emotional outburst or during physical activity.

Extraordinary contractions of the ventricular myocardium against the background of morphological disorders of the heart, as a rule, are multiple (polymorphic) in nature, but for the patient they often occur without clinical manifestations. Symptoms develop with significant physical activity and disappear in a lying or sitting position. This type of right or left ventricular arrhythmia develops against the background of tachycardia and is characterized by:

• suffocation;
• feeling of panic, fear;
• dizziness;
• darkening of the eyes;
• loss of consciousness.

Diagnostics

The main method for diagnosing frequent ventricular extrasystole is recording an electrocardiogram at rest and a 24-hour Holter monitor. A daily study of the ECG helps to determine the number and morphology of pathological contractions, how they are distributed throughout the day, depending on various factors and conditions of the body (period of sleep, wakefulness, use of drugs). In addition, if necessary, the patient is additionally prescribed:

• electrophysiological study of the myocardium by stimulating the heart muscle with electrical impulses while simultaneously observing the result on an ECG;
• echocardiography or ultrasound (ultrasound) - determination of the morphological cause of arrhythmia, which is usually associated with hemodynamic disturbances;
• laboratory tests to determine fast phase protein, electrolytes, levels of hormones of the pituitary gland, adrenal glands and thyroid gland, the amount of globulins.

Ventricular extrasystole on ECG

The main methods for diagnosing heart rhythm disturbances are electrocardiography and Holter monitoring of myocardial function (impulses of the conduction system). Ventricular extrasystole, when deciphering the studies performed, is manifested by the following signs:

• expansion of the QRS complex;
• absence of P wave;
• extraordinary premature appearance of an altered QRS complex;
• complete compensatory pause after a pathological QRS complex;
• T wave deformation (rare);
• ST segment expansion.

Treatment of ventricular extrasystole

In order to achieve the desired effect in the treatment of extrasystole, it is necessary to prescribe a set of therapeutic measures:

• Prohibition on the consumption of alcoholic beverages, strong tea, coffee, and smoking.
• Recommendations to adhere to the basic principles of proper nutrition and increase the proportion of foods with a large amount of potassium in the diet (potatoes, seafood, beef, etc.) and other necessary microelements for normal heart function.
• Refusal of heavy physical activity.
• If the patient often experiences stress and insomnia, it is recommended to use light soothing herbal preparations (motherwort, lemon balm, peony tincture) or sedatives (valerian tincture).
• If indicated, the patient is referred for surgical treatment.
• Antiarrhythmic drugs are prescribed.
• It is recommended to use medications that support heart function and vitamin and mineral complexes.

Drug therapy

The drug treatment regimen is prescribed individually and depends entirely on the type of pathology and cause, frequency of arrhythmias, and the presence of other concomitant systemic chronic diseases. Antiarrhythmic drugs that are used for pharmacological therapy of PVCs are divided into the following categories:

• blockers of sodium, calcium and potassium channels (Novocainamide);
• beta-blockers (Concor-Cor);
• antihypertensive drugs (Anaprilin);
• thrombolytics (Aspirin).

Standard pharmacological therapy includes the use of the following pharmacological drugs:

1. Cordinorm. A drug based on the substance bisoprolol, which has antiarrhythmic and hypotensive effects. Prescribed for the treatment of heart rhythm disorders. The advantage of the drug is its rapid action and versatility of use, but the disadvantage is the high probability of developing side effects.
2. Aspirin. Tablets containing acetylsalicylic acid. The medication improves blood supply to the myocardium and has a vasodilating effect. Aspirin is indicated for coronary heart disease and myocardial infarction. The advantage of the medicine is the versatility of its use, and the disadvantage is the frequent development of allergic reactions.
3. Novocainamide. A medicine whose active ingredient is procainamide. The drug significantly reduces the excitability of the heart muscle and suppresses pathological ectopic foci of excitation. Medication is prescribed for various cardiac arrhythmias. The advantage of the medicine is the rapid effect it produces, and the disadvantage is the need to accurately calculate the dosage to prevent the development of side effects.

A patient who has started drug treatment is recommended to have a control electrocardiogram after 2-3 months. If extraordinary cardiac contractions become rare or disappear, then the therapeutic course is gradually, under the supervision of a doctor, canceled. In cases where the result has not changed or improved slightly during treatment, the medications are continued without changes for several more months. In case of a malignant course of the disease, medications are taken by the patient for life.

Surgical intervention

The indication for surgical treatment of arrhythmia is the ineffectiveness of drug therapy. As a rule, this type of elimination of pathology is recommended for those patients who have organic heart damage in combination with impaired hemodynamics. The following types of surgical intervention exist:

• Radiofrequency ablation (RFA). During the procedure, the surgeon inserts a small catheter into the heart cavity through a large vessel and uses radio waves to cauterize problem areas of the myocardium. To make it easier to find the affected area, electrophysiological monitoring is used. The effectiveness of RFA, according to statistics, is 75-90%. The operation is contraindicated for elderly people (over 75 years old).
• Installation of a pacemaker. This device is a small box that contains electronics and a battery that lasts between 8 and 10 years. Electrodes extend from the pacemaker, which the doctor attaches to the ventricle or atrium during surgery. They send impulses that cause the heart muscle to contract. Such an electronic device helps the patient get rid of various rhythm disturbances and return to a full life. Among the disadvantages of installing a pacemaker is the need to replace it.

Folk remedies

Traditional medicine recipes are used to treat functional type extrasystole. If there are serious organic changes in the myocardium, you should consult a cardiologist, since some alternative methods of treatment have contraindications for use. Remember that the use of folk remedies will not replace full-fledged drug therapy or surgery. At home, you can prepare the following folk remedies for the treatment of arrhythmia:

1. A decoction of valerian root, calendula and cornflower. You need to take 1 tbsp. mix all the ingredients, add water and bring to a boil, then cool. Strain and take half a glass in the morning and evening for 10-12 days. Use this product with caution for people prone to allergies.
2. Horsetail infusion. Dry horsetail grass in the amount of 2 tbsp. it is necessary to brew with three glasses of boiling water and leave for 6 hours. Take the product 5-6 times a day, 1 tsp for a month. It is not recommended to use the infusion for patients who suffer from chronic renal failure.
3. Radish juice with honey. Raw radish must be grated and squeezed through cheesecloth. Add 1 tbsp to the resulting juice. honey Take 2 tsp. three times a day for a week.

Forecast and prevention of frequent ventricular extrasystole

The prognosis for the course of ventricular extrasystole depends on its form, the presence of morphological pathology of the heart tissue or hemodynamic disorders. Functional idiopathic and single extraordinary contractions of the myocardium do not pose a threat to the health or life of the patient. Extrasystole, which develops against the background of organic damage to the heart, in the absence of treatment, significantly increases the risk of developing organ failure, sudden death due to the development of tachycardia, atrial fibrillation and supraventricular arrhythmias, and fibrillation.
