Early Repolarization Found on Routine Electrocardiograms: Risk and Management

Early repolarization (ER) pattern is a prominent J point (end-QRS notch or slur) with an elevation ≥0.1 mV in two or more contiguous leads (excluding V1-V3) in a 12-lead electrocardiogram (ECG). Furthermore, the QRS duration is required to be <120 ms (measured in leads in which J point elevation
