TABLE 1

Early repolarization: High-risk features

J-point distribution	Lateral distribution is deemed low-risk compared with inferior and global distribution across all leads
J-wave amplitude	Amplitude ≥ 0.2 mV
ST-segment morphology	Horizontal or downsloping ST segment
QRS notching	Notching of the terminal portion of the QRS is more prevalent in patients with idiopathic ventricular fibrillation
