Immediate electrical storm of Torsades de Pointes after CRT-D implantation in an ischemic cardiomyopathy patient

摘要: Cardiac resynchronization therapy with an implantable cardioverter-defibrillator (CRT-D) is the preferred treatment for patients severe heart failure, dyssynchrony, and increased risk of sudden cardiac death or primary ventricular arrhythmia survivors. Rarely, left epicardial pacing can induce tachyarrhythmia rather than a beneficial effect. We describe ischemic cardiomyopathy patient who underwent CRT-D developed sustained torsades de pointes (TdP) immediately after switching to biventricular (BVP) mode. Here, TdP possibly owing change in dispersion repolarization ventricle myocardium. The diagnosis management BVP-induced discussed.
