Early repolarization (ER) in the inferior/lateral leads predicts mortality, but whether ER is a specific sign of increased risk for arrhythmic events is not known. The purpose of this study was to study the association of ER and arrhythmic events and nonarrhythmic morbidity and mortality. We assesse...
