1. Benign early repolarization
Seen in fit young people
less common in the over 50s, rare in the over 70s
Widespread ST segment elevation that may mimic pericarditis or acute MI
Characteristic notched J Point
Possibly related to high sympathetic tone on heart 

2. Notched J point :Fish hook appearance

3. ECG finding
