title: The appearance of negative U waves in the precordial leads during balloon occlusion of the long posterior descending artery.
abstract: This report presents a patient in which balloon occlusion of the posterior descending artery wrapping the apex produced negative U waves in leads V(4-5). This case report demonstrates, for the first time, that negative U waves in the precordial leads can appear by occlusion of the long posterior descending artery.
