The effect of cardiac resynchronisation therapy on ventricular tachycardias (VT) has not been well established. This case-report demonstrates the favourable impact of biventricular pacing on ventricular arrhythmias. In 2004, a patient with dilated cardiomyopathy and ICD since 1999 was admitted to our Division for multiple VT. While left ventricular function was markedly reduced and mitral regurgitation was severe, he was asymptomatic for heart failure. Amiodarone was not administered on account of a documented proarrhythmic effect. The patient's ICD was upgraded to an ICD-biventricular system. After upgrading, a significant reduction in the number of VT was noted.
心脏再同步治疗对室性心动过速（VT）的影响尚未完全明确。本病例报告展示了双心室起搏对室性心律失常的有利影响。2004年，一名自1999年起患有扩张型心肌病并植入植入式心律转复除颤器（ICD）的患者因多次发生室性心动过速入住我科。尽管左心室功能显著降低且二尖瓣反流严重，但他并无心力衰竭症状。由于有记录显示胺碘酮有致心律失常作用，故未使用该药物。该患者的ICD升级为ICD-双心室系统。升级后，室性心动过速的发作次数显著减少。
