Title: The J-wave conundrum: Early repolarization and Brugada syndrome
Abstract: In this issue of HeartRhythm, Takagi et al 1 Takagi M, Aonuma K, Sekiguchi Y, Yokoyama Y, Aihara N, Hiraoka M. The prognostic value of early repolarization (J wave) and ST-segment morphology after J wave in Brugada syndrome: multi-center study in Japan. Heart Rhythm 2013;10:533–539. Google Scholar evaluate the prognostic value of inferolateral J-point elevation in a large cohort of patients with Brugada syndrome (BrS). Inferolateral J-point elevation followed by a horizontal ST segment is associated with an increased risk of arrhythmic events in both patients groups with and without a history of aborted sudden cardiac death by ventricular fibrillation (VF). The authors conclude that the combination of electrocardiographic patterns may help identify patients with BrS with a highly arrhythmogenic substrate. The article by Takagi once more shows the intertwinement of BrS and early repolarization syndrome. 1 Takagi M, Aonuma K, Sekiguchi Y, Yokoyama Y, Aihara N, Hiraoka M.
