We describe a patient with Brugada syndrome in whom J point and ST‐segment elevation in leads V 1 and V 2 were augmented by atrial pacing and intravenous administration of propranolol or cibenzoline. Significant T wave alternans with a 2:1 appearance of terminal negative T wave was observed in the absence and presence of atrial pacing after the administration of cibenzoline. The cellular mechanism responsible for T wave alternans. beat‐to‐beat appearance of terminal negative T wave and augmented J point and ST‐segment elevation is discussed
