摘　　要：The implantable cardioverter-defibrillator(ICD)is a key component in the primary pre-vention of sudden cardiac death in patients with ischemic cardiomyopathy.Appropriate device programming is pivotal in maximizing the benefit as well as minimizing any proarrhythmic effect of dev-ice therapy.It is even more so for patients who require pacing for bradycardia,in which interaction of the de-vice with intrinsic rhythm may generate unexpected consequences.We report a case of pacing induced ven-tricular tachycardia as a result of complex interplay of competitive atrial pacing,atrial and ventricular func-tional undersensing,ventricular functional loss of capture,and the AutoCapture®algorithm specific to Abbott devices.
