Abstract:
The 12-lead electrocardiogram of a 17-year-old African professional soccer player had signs of left ventricular (LV) hypertrophy and deeply inverted T waves in the inferior and precordial leads. Two-dimensional echocardiography showed mild LV hypertrophy with normal cavity size consistent with nonobstructive hypertrophic cardiomyopathy. After 5 months of complete discontinuation of training, the electrocardiogram normalized; however, the echocardiogram was unchanged. Subsequently, and contrary to our advice, the athlete resumed training and professional soccer. One year later the electrocardiogram again showed a similar and markedly abnormal pattern without cardiac dimensional changes.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
