Augmentation of J Waves and Electrical Storms in Patients with Early Repolarization

Abstract

To the Editor: Early repolarization, consisting of an elevation of the QRS–ST junction (J point), QRS notching or slurring (J wave), and a tall, symmetric T wave, is generally considered to be benign.¹ On the basis of preclinical experimental evidence, it has been suggested that some forms of early repolarization seen in the clinic may not be benign, especially when associated with the occasional appearance of J waves or ST-segment elevation.² Sporadic case reports and basic electrophysiological research have suggested a critical role of the J wave in the pathogenesis of idiopathic ventricular fibrillation.^3,4 Clinical evidence in support of . . .
