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.

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

In the absence of genetic predisposition, repolarization-accelerating factors that coexist may produce clear ECG signs of early repolarization without inducing sufficient abnormality to cause ...
