Syndrome nadzheludochkovogo comb is usually considered not a separate disease, but only a phenomenon of ECG (electrocardiogram), a special version of the norm.
Doctors, as a rule, recommend parents whose children have seen such a syndrome, do not worry, as it does not outgrow the heart disease.
Causes of the syndrome of supraventricular scallop
Nadzheludochkovym scallop called one of the many muscle beams that are located in the heart (between the anterior and posterior parts of the right ventricle). At the moment, the causes of the supraventricular scallop syndrome are not found. As a rule, this phenomenon is noticeable in children, but experienced pediatricians do not recommend experiencing it, especially if there are no murmurs in the heart or other phenomena.
Pathogenesis
The electrocardiogram in a child is significantly different from the ECG of an adult. As a rule, PQ and QT intervals can be shorter, QRS is smaller, and sinus arrhythmia is sometimes noticeable. This can be explained by the fact that in childhood, the heart rate is higher than in adults. Sometimes on this background the doctor can notice the so-called supraventricular scallop syndrome.
Since it is not a pathology and is not considered a separate disease, usually such a phenomenon is left without attention. Such a syndrome usually disappears with time, so it does not require treatment.
Symptoms of the syndrome of supraventricular scallop
External symptoms that could be seen with the naked eye, usually not. After passing the ECG in children up to six years with the syndrome of the supraventricular scallop:
- Domination of the right ventricle above the left.
- The electrical axis of the heart is markedly deviated to the right side.
- Voltage of the teeth of the ventricular complex is greatly overestimated.
- Thoracic wall too thin.
- Sometimes up to 16 years you can see negative teeth T in leads V1-V2.
First signs
Unfortunately, the first signs of the supraventricular scallop syndrome are absent. Sometimes a child may have an increased heartbeat, often a feeling of fatigue, a pain in the chest after severe physical exertion. In this case, parents usually show the baby to the doctor who conducts the electrocardiogram. Only with its help you can see the changes in the ventricle.
Syndrome nadzheludochkovogo comb in adults in adults is quite rare. This is due to the fact that the walls of the chest after 18 years are no longer so thin as in childhood. But in very rare cases, the ECG still shows the presence of a similar syndrome. Do not worry. This phenomenon is a variant of the norm and is not considered a disease or pathology. Usually, with the right rhythm of life, this syndrome passes by itself, without any intervention.
A similar phenomenon is much more common in children than in adults, since the chest wall is not yet sufficiently compacted. This phenomenon does not cause any unpleasant symptoms and does not require medical treatment. As a rule, it either passes itself with time, or grows into an incomplete blockade of the bundle of the Hyis, which also does not heal.
Complications and consequences
Speaking about the consequences of the supraventricular scallop syndrome, it means only the possibility of overgrowing this phenomenon into an incomplete blockade of the bundle of His. Usually, such a pathology does not cause fears from doctors, so it does not require any specific method of treatment. Sometimes patients try, from time to time, to be observed by a professional to see the development of pathology.
In very rare cases, an incomplete bundle bundle blockage, which sometimes develops from the supraventricular scallop syndrome, can become a progressive heart disease and cause a complete cardiovascular blockade.

Diagnostics of the syndrome of supraventricular scallop
The only way to see violations in the ventricle is to conduct an electrocardiogram or an ECG. This abbreviation is familiar to many people, as it is often used in a variety of diseases. This method is based on recording the electrical activity of the heart.
When diagnosing the syndrome of supraventricular scallop, there is no need to take tests.
Instrumental diagnostics
Syndrome supraventricular scallop can be diagnosed only with the help of ECG. This is an accessible, simple and informative method that is carried out not only by hospitals, but also in small outpatient clinics or even ambulances. In simple terms, an electrocardiogram is a dynamic record of an electric charge, thanks to which our heart is shortened.
That is why with the help of ECG you can see any changes in the work of the cardiovascular system.
ECG signs
In early childhood, the instability of the QRS amplitude in the most diverse cardiac leads is often noticeable. This phenomenon is called a physiological alternative. It is explained by the lability of the electrophysical processes that occur in the myocardium.
If a completely healthy child during ECG observed splitting of this complex in the lead VI, then this phenomenon is called the syndrome supraventricular scallop. Interestingly, it is noted in 30% of children. Especially often it is observed in children up to six years old.
On the ECG, this syndrome manifests itself in the lead VI, sometimes in the extreme right leads V3R and V5R. It is considered a deformation of the rSr 'type of the QRS complex with a narrow and low-amplitude tooth r'. Rarely, but it happens that the deformation has the form of serration on the ascending knee S of the tooth.
In other leads, such deformations are not noticeable. In this case, the duration of QRS is not considered a deviation from the norm. The phenomenon is caused by the fact that the right hypertrophic supraventricular comb is excited. Sometimes the location of the heart in the chest plays an important role in the development of such a syndrome.
Sometimes the syndrome of the supraventricular scallop is diagnosed by other non-invasive electrocardiologic methods. For example, sometimes electrocardiography is used. It is based on recording the bioelectrical parameters of the heart.

Treatment of the syndrome of supraventricular scallop
Since this phenomenon is not a disease or pathology, it does not require treatment.
To improve the general condition, as well as the best work of the cardiovascular system, you can use special vitamins:
- Vitrum Cardio Omega-3. A hypolipidemic drug that helps lower triglycerides, cholesterol and lipoprotein levels in the blood. If the syndrome of supraventricular scallop is observed in adults, you can take these vitamins. Active active substance of the agent is polyunsaturated fatty acids. The drug helps support the cardiovascular system of the body and improve the work of the heart.
- Antiox. In the composition of this multivitamin drug you can find: vitamin A, selenium, vitamin E, vitamin C. Note that this is a strong enough tool, so it should not be taken for a long time.
Forecast
Usually, the syndrome of the supraventricular scallop passes independently, without any interference from the side. Even if this does not happen, you do not have to worry and continue to live your life.
Sometimes (but in very rare cases) this syndrome grows into an incomplete blockade of the bundles of His. This phenomenon is considered a non-serious disease that does not require treatment. In a complete blockade, it can not grow.
