Electrocardiographic analysis of early Repolarization as Abenign variant Inathletes

Aim: To analyse the prevalence and pattern of early repolarization in athletes and non-athletes. Study design: Retrospective study Sample size: • Total sample of60 • Athletes30 • Non-athletes30 Inclusion criteria for Study group: 30 subjects who are involved in sports should haveundergone atleast2-3hoursofpracticeperdayfor5daysinaweekforminimum of 2years Inclusion criteria for Control group: The control consists of 30 healthy volunteers matched forage and BMI. All of them had a relatively sedentary lifestyle. Exclusion criteria (Study and Control group): • H/Ohypertension, • H/Ocoronaryartery disease • H/Opulmonary disease • H/O smoking, alcohol • H/O drug (like antihistamine that causes prolongation of QT interval) • Past history of cardiac surgery and family history of cardiovascular disease. Materials and methodology: For both athletes and non-athletes ECG was taken in lying position, ECG paper having 1mm and 5mm squares is used. The tracing is usually made at a standard recording speed of 25mm/sec. The physical examination including height, weight, blood pressure and pulse rate were examined for all the participants and the ST segment morphology and amplitude of deviation from the isoelectric line was analysed. Results: Athletes showed more prevalence of ST segment elevation with concave upwards type of morphology in leads V3-V6 than non-athletes. Conclusion: Early repolarization which is a benign variant is more prevalent in athletes.
