Early repolarization is not an uncommon finding on EKG, occurring in 2% to 5% of the population, often in men, young adults, blacks, and athletes. Although most often thought to be benign, SOME forms of early repolarization may be potentially cause dangerous arrhythmias.
If ECG findings of early repolarization are “localized to the inferolateral leads”, causes that include the long-QT syndrome, the short-QT syndrome, the Brugada syndrome, and arrhythmogenic right ventricular dysplasia need to be excluded.
