Benign early repolarization (BER) or early repolarization is found on an electrocardiogram (ECG) in about 1% of those with chest pain.[2] It is diagnosed based on an elevated J-point / ST elevation with an end-QRS notch or end-QRS slur and where the ST segment concave up. It is believed to be a normal variant.[2]

Benign early repolarization that occurs as some patterns is associated with ventricular fibrillation. The association, revealed by research performed in the late 2000s, is very small.
