Ventricular arrhythmia (VA) is a rare complication of cardiac resynchronization therapy (CRT). Little is known about ventricular proarrhythmia related to the pacing vector of CRT. This case report describes the elimination of ventricular arrythmia using biventricular pacing in a patient with VT-storm related to LV only pacing as part of the AdaptivCRT algorithm (Medtronic Inc). Simultaneous biventricular pacing was effective in eliminating polymorphic ventricular tachycardia. Changing the pacing vector is a noninvasive treatment strategy that should be considered to manage VA due to CRT.
室性心律失常（VA）是心脏再同步治疗（CRT）的罕见并发症。关于与 CRT 起搏向量相关的室性促心律失常知之甚少。本病例报告描述了使用双心室起搏消除与 LV 仅起搏相关的 VT-风暴患者的室性心律失常的情况，该起搏作为 AdaptivCRT 算法（美敦力公司）的一部分。同时进行双心室起搏可有效消除多形性室性心动过速。改变起搏向量是一种非侵入性治疗策略，应考虑用于因 CRT 导致的 VA。
