OBJECTIVES This study sought to determine whether T-wave alternans (TWA) induced by anger in a laboratory setting predicts future ventricular arrhythmias in patients with implantable cardioverter-defibrillators (ICDs). BACKGROUND Anger can precipitate spontaneous ventricular tachycardia/ventricular fibrillation and induce TWA. Whether anger-induced TWA predicts future arrhythmias is unknown. METHODS Sixty-two patients with ICDs underwent ambulatory electrocardiography during a mental stress… CONTINUE READING
