摘　　要：非缺血性心肌病室性心动过速的发病机制主要是瘢痕折返,瘢痕常累及心肌中层及心外膜。非缺血性心肌病室性心动过速多次消融的累积成功率为70%~80%,但LMNA基因突变心肌病及肥厚型心肌病扩张期室性心动过速消融的成功率较低。非缺血性心肌病室性心动过速导管消融手术的并发症发生率并不高于缺血性心肌病室性心动过速。术中晚电位消除+室性心动过速不能被诱发这一消融策略可增加手术的成功率。现对非缺血性心肌病室性心动过速导管消融的有效性及安全性做一综述。The pathogenesis of ventricular tachycardia in non-ischemic cardiomyopathy is mainly scar-related reentry,which often involves the intramural and epicardium.The cumulative success rate of multiple ablation of ventricular tachycardia in non-ischemic cardiomyopathy can reach about 70%~80%,but the success rate of LMNA mutation cardiomyopathy and the dilated phase of hypertrophic cardiomyopathy is low.The complication rate of catheter ablation for ventricular tachycardia with non-ischemic cardiomyopathy is not higher than that of ventricular tachycardia with ischemic cardiomyopathy.The ablation strategy of late potential ablation and ventricular tachycardia noninducibility can increase the success rate.This article reviews the efficacy and safety of catheter ablation for ventricular tachycardia in non-ischemic cardiomyopathy.
