What do we know about the "malignant form" of early repolarization?

Abstract

There is an urgent need to identify electrocardiographic characteristics that differentiate the "benign early repolarization pattern" from "malignant early repolarization." In a previous paper, we considered the different electrocardiographic elements of the early repolarization pattern and analyzed how they confer important prognostic information. In the present article, we review more recent information regarding the importance of the contour of the ST segment, with special emphasis on the currently termed malignant form and its value for risk stratification in early repolarization.
