La repolarización precoz en el electrocardiograma del futbolista. Prevalencia, características y evolución. / [Early repolarization in soccer players ECG. Prevalence, characteristics and evolution].

ABSTRACT

UNLABELLED Early repolarization (RP) on the electrocardiogram (ECG) of the athlete has been considered a benign finding. In some publications it has been associated with increased risk of sudden death. The objectives of this study were to evaluate the prevalence of infero-lateral RP in a population of trained players, to describe variables associated with this pattern and investigate the occurrence of events in the follow up. ECG of players with a normal cardiovascular physical examination and without family and personal history of heart disease, were analyzed. RP was considered the J-point elevation = 0.1 mV over baseline in at least 2 inferior and / or lateral precordial leads, associated or not with positive deflection or notch in the end of the QRS. RP is related to the voltage of R in V5 or V6, the PR interval, heart rate (HR) and age. They were contacted at 60 ± 5 months after the initial assessment ECG. STATISTICS chi square and t test for unpaired data. We evaluated ECG of 210 soccer players, of European-South American origin, with high intensity training. Age 18 ± 4.6 years. The RP ECG was present in 86 (40.9
