Note: The ECG changes of pericarditis must be distinguished from those of early repolarization. The ST elevation seen in early repolarization is very similar: diffuse and concave upward.

For over 60 years, the ECG pattern called 'early repolarization' , which affects about five percent of people, has been considered a normal variant 1. But that view is coming into question.

High vagal tone in athletes results in bradycardia and repolarization anomalies on the resting ECG. Bradycardia permits enhanced diastolic filling, which in turn results in highly effective ...
