Electrocardiographic and Blood Electrolytes Findings in Athletic Students of Sports Academy in Bangladesh

Athletes require regular intensive exercise and training, responsible for structural and functional changes in their hearts, which are reflected on electrocardiogram (ECG) findings [1]. The changes may include elevated QRS voltage, QRS axis shifts, ST-T wave changes that are consistent with early repolarization, bradyarrhythmias, first-degree and Mobitz type-1 atrioventricular block and inverted T-waves [2]. The most common finding in athlete’s ECG is sinus bradycardia with resting heart rate as low as 40 beats per minute. Also trained athletes show following alterations of their 12-lead ECG. The alterations are increase in R or S wave voltages, ST-segment elevation, T-wave changes (either tall, flattened or frankly inverted), and deep Q waves [3].
