[FEATURES OF EARLY REPOLARIZATION SYNDROME DEPENDING ON EVIDENCES OF HEART HYPERTROPHY IN PROFESSIONAL ATHLETES]

A syndrome of early repolarization, common in professional athletes, has recently been considered as a possible predictor of acute arrhythmias. It is known that for this category of young people the development of compensatory hypertrophy of the heart is also common. The aim of the study was to investigate the features of early ventricular repolarization in professional athletes, depending on the presence of signs of cardiac hypertrophy. The study included 28 high-level competition athletes who had regular intensive physical activity for at least six months. Syndrome of early repolarization was diagnosed on the basis of ECG registration, in case of elevation of the J-point on 1 mm and more above the isoelectric line in the lower or lateral leads was detected. Diagnosis of cardiac hypertrophy was established by electrocardiography and echocardiography. On the background of high prevalence of early repolarization syndrome in professional athletes, we did not reveal the statistically significant relationship between its presence and cardiac hypertrophy. However, the combination of these two syndromes in the examined athletes was accompanied by a statistically significant shortening of the corrected QT interval, the last, in a case of the presence of certain anamnestic data, may be one of the risk factors for acute arrhythmias. This necessitates a deeper examination of such patients and monitoring of them. Further studies are needed to determine the prognostic value of early repolarization in athletes with cardiac hypertrophy.
