Syndrome of early repolarization of the ventricles is a medical term and means only a change in the patient's electrocardiogram. External symptoms are not a violation. Previously, this syndrome was considered a variant of the norm, and therefore not having a negative effect on life.
To determine the characteristic symptoms of the syndrome of early repolarization of the ventricles, a variety of studies were carried out, but no results were obtained. Violations in the ECG, which correspond to this anomaly, occur even in fully healthy people who do not have complaints. They are also in patients who have cardiac and other pathologies (they complain only about their underlying illness).
Many patients with whom doctors have discovered the syndrome of early repolarization of the ventricles, often have a history of the presence of such types of arrhythmias:
- Ventricular fibrillation;
- Tachyarrhythmia of the supraventricular divisions;
- Ventricular extrasystole;
- Other types of tachyarrhythmias.
Similar arrhythmogenic complications of this syndrome can be considered a serious threat to health, as well as the life of the patient (even death can provoke). World statistics show many deaths due to asystole in ventricular fibrillation, which appeared precisely because of this anomaly.
Half of the subjects with this phenomenon have cardiac dysfunctions (systolic and diastolic), which cause central hemodynamic problems. The patient may develop cardiogenic shock or hypertensive crisis. Also, there may be pulmonary edema and shortness of breath of varying severity.
The researchers believe that the appeared at the end of the QRS complex is a jagged delta wave. Additional confirmation of the presence of additional electrically conductive pathways (they are the first cause of the phenomenon) is the reduction of the PQ interval in many patients. In addition, the syndrome of early repolarization of the ventricles can arise due to an imbalance in the mechanism of electrophysiology, responsible for the change in the functions of de-and repolarization in different areas of the myocardium, which are located in the basal parts and the cardiac apex.
If the heart is working normally, then these processes occur in the same direction and in a certain order. Repolarization starts from the epicardium of the cardiac base and terminates in the endocardium of the cardiac apex. If there is a violation, the first signs are a sharp acceleration in the subepicardial parts of the myocardium.
The development of pathology depends very much on dysfunction in the autonomic NA. Vagal genesis of anomalies is proved by conducting a sample with moderate physical activity, as well as a drug test with an isoproterenol preparation. After this, the patient stabilizes the ECG, but the ECG signs during sleep at night worsen.
Syndrome of early repolarization of ventricles in pregnant women
This pathology is characteristic only when recording electro-potentials on the ECG and in an isolated form does not affect cardiac activity at all, and therefore does not need treatment. It is usually noticed only if it is combined with fairly rare forms of severe cardiac rhythm disturbances.
Numerous studies have confirmed that this phenomenon, especially accompanied by fainting caused by heart problems, increases the risk of sudden coronary death. In addition, the disease can be combined with the development of supraventricular arrhythmias, as well as a decrease in hemodynamics. All this can result in heart failure. These factors have also become a catalyst for the fact that cardiologists are interested in the syndrome.
The syndrome of early repolarization of the ventricles in pregnant women during the gestation process and the fetus is not reflected in any way.
Syndrome of early repolarization of ventricles in children
If your child is diagnosed with a syndrome of early repolarization of the ventricles, you should undergo such examinations:
- Taking blood for analysis (vein and finger);
- Average portion of urine for analysis;
- Ultrasound examination of the heart.
The above surveys are necessary to exclude the possibility of asymptomatic development of disturbances in work, as well as conduction of heart rhythm.
The syndrome of early repolarization of the ventricles in children is not a sentence, although after its detection it is usually necessary to go through several times the process of examining the heart muscle. The results obtained after ultrasound should be assigned to a cardiologist. He will determine whether the child has any pathologies in the area of the muscles of the heart.
A similar anomaly can be observed in children who had problems with cardiac circulation even during the embryonic period. They will need regular checkups with the cardiologist.
To ensure that the child does not feel attacks of accelerated heartbeat, you should reduce the number of physical exertion, and also make them less intense. It will not prevent him and the observance of the correct diet, and the maintenance of a healthy lifestyle. It will also be useful to protect the child from various stresses.
