Stage III: T waves are inverted, and the ECG is otherwise normal. Stage IV ... The ratio of the T wave amplitude to the ST elevation should be greater than 4 if early repolarization is present ...

These ECG findings in athletes are considered normal, physiological adaptations to regular exercise and do not require further evaluation (box 1). Convex (‘domed’) ST segment elevation combined with T ...
