Early repolarization is not an uncommon finding on EKG, occurring quite rarely (in 2% to 5% of the population), often in men, young adults, blacks, and athletes. Although most often 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.
