Early repolarization: an evolving concept for the past 70 years.

Abstract

For more than 70 years, early repolarization has been considered to be a common normal variant. In the general population, the prevalence ranges between 5 and 13%, and in athletes, a rising trend is observed from 20 to 90%. Nevertheless, from the latter half of the 1990s, a growing number of case reports, series, observational and prospective studies reported that the presence of various electrocardiographic patterns attributed to early repolarization may constitute a potential marker for the increased risk of sudden death in otherwise normal individuals, casting a dark shadow on this ECG peculiarity. This review provides a historical summary of the evolution of the concept of early repolarization from its original description to the latest works and a guide to help physicians in evaluating individuals with this common electrocardiographic pattern.
