Syndrome of supraventricular scallop: symptoms, diagnosis, treatment

Sometimes in the conclusions of a cardiologist, after studying the cardiogram, you can see a record - "supraventricular scallop syndrome". What does it mean? First of all, do not be afraid. After all, this is a variant of the norm, and in no case is it a disease. If we look at it literally, then this syndrome is just a phenomenon, manifested exclusively by changes in the ECG.

Causes

Why there is a syndrome of supraventricular scallops, scientists have not figured it out yet. This anatomical formation is a bundle of muscle fibers that pass through the middle of the right ventricle.

On an electroencephalogram, the syndrome looks like a QRS tooth splitting in the fourth lead. It occurs only in thirty percent of cases of examination of clinically healthy preschool children.

For the appearance of this pathology the role of the heart, electric potentials of the right and left ventricles play a role .

Pathogenesis

The cardiogram of the child has its own physiological and pathological features. It is worth saying that the changes on it depend on the age of the patient, when there is a single norm for an adult person. Among the "childish" features, one can list the shortening of the PQ and QT intervals, the GRS complex also narrows, sometimes an arrhythmia can occur, with the positive tooth P.

Pathophysiologists explain these phenomena by the fact that a child's heart beats more often than an adult's. The potentials of actions are shifted and overlap. Or excitement does not have time to cover all the cardiomyocytes before contraction - so on the ECG artefacts appear.

Syndrome nadzheludochkovogo scallop - one of such physiological phenomena. Its presence does not testify to any pathology, therefore doctors do not accent on it attention and in due course the child outgrows it.

Symptoms

Syndrome nadzheludochkovogo scallop absolutely does not manifest itself. Some children may experience a feeling of fatigue, fatigue after physical exertion, a feeling of heartbeat - such complaints cause the child to go to the doctor. And the expert already on the cardiogram sees characteristic changes.

Syndrome nadzheludochkovogo comb in adults is rare, but even if it occurs when removing the ECG, then this is not a reason for panic, because it is considered by experts as a variant of the norm. Even in the absence of treatment, this phenomenon completely disappears and does not cause any concern.

Complications and consequences

Syndrome nadzheludochkovogo comb in a child can both go through with time, and turn into an incomplete blockade of the stem of the bundle. But in this case, too, it is not worth worrying, because such a condition does not cause serious changes in the myocardium and does not affect the quality of life of the child. It is recommended, as a rule, periodically undergo a medical examination in order to follow the progression of pathology.

It is extremely rare cases when an incomplete blockade develops into more serious defects, such as a complete transverse blockade of the bundle of Guiss and others.

Diagnostics

The only way to see the syndrome of the supraventricular scallop is ECG. This method is available at any hospital or polyclinic. An electrocardiogram is a graphic record of a successive change of electrical potentials appearing in cardiomyocytes.

In young children, the nervous system has not yet been "calibrated", so it is possible to register various abnormalities on the ECG. For example, this may be a change in the configuration and amplitude of the prongs in the thoracic leads. But in order to confirm the presence of pathology, it is not enough to have the result of one study.

Children who have a pediatrician who suspected a violation in the work of the heart are put on dispensary records for this disease and, without fail, once a year or six months are examined by a cardiologist. This allows you to observe the dynamics of the development of the process, as well as to notice deterioration in time.

Treatment

Syndrome nadzheludochkovogo comb does not require treatment, until it does not feel uncomfortable to the child. The phenomenon itself passes when the patient grows up, and the intervention of the doctor can only worsen the situation. But if parents insist on carrying out of therapy, it is possible to advise to accept following preparations:

• Essential fatty acids, for example, omega-3. They help to reduce the amount of lipids in the blood, in addition, these substances strengthen the walls of blood vessels and improve the work of the heart.
• "Antiox" - a multivitamin preparation containing vitamins A, E, C, as well as trace elements. Do not abuse these complexes, because they develop an allergic reaction.

But it is best not to stuff the child with medicines, but to ensure that his diet receives all the necessary substances that are contained in the following foods: dietary meat (poultry, veal), fish of fatty varieties, olive oil, nuts, fresh vegetables and fruits (preferably seasonal, not Hothouse). If there is enough physical exercise with this diet, the phenomenon will pass by itself.

Forecast

The prognosis for life and health of such children does not cause fear. Even without medical assistance, the syndrome itself passes with age. This happens unnoticed for the child and should not cause concern to the parents.

Even in those rare cases when the phenomenon develops into an incomplete blockade of the bundle of His, this is not regarded by clinicians as a severe conduction disorder. Regular monitoring of the condition of the heart will help to avoid surprises.
