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.

This ECG 'variant' is relatively common and ... causing extra beats that can trigger ventricular fibrillation. The early repolarization pattern is more common in male, young (<40 years) and ...

Diffuse T wave inversion is stage III of the ECG changes in pericarditis. Pericarditis can be distinguished from early repolarization ... a “sine wave” pattern ensues. Hyperacute T waves ...
