摘要 对8例起源于特殊部位的特发性室性心动过速(简称室速)的心电图特征及其导管射频消融的方法学进行了分析。8例患者中男5例、女3例，心动过速史3～20年。室速形态呈右束支阻滞者4例、呈左束支阻滞者4例；电轴右偏6例、左偏2例。结果：8例患者均射频消融成功，消融靶点2例位于左室流出道左冠窦内，距左冠状动脉主干开口约1 cm，2例位于左室游离壁，2例位于左前分支近心尖部，2例位于右室流入道游离壁。结果提示导管射频消融对起源于特殊部位的室速也具有较高的成功率；左室流出道室速(LVOT-VT)的心电图具有一定的特殊性，对LVOT-VT进行射频消融时应避免累及冠状动脉左主干。

Radiofrequency Catheter Ablation for Idiopathic Ventricular Tachycardia of Atypical Site.

LIU Xu,SONG Guan-ying,CHENG Yong-hai,et al.

This paper discussed the characteristic of electrocardiography and catheter ablation for idiopathic ventricular tachycardia (VT) of atypical site.Of the 8 patients with VT and no structural heart diseases were 5 male and 3 female,tachycardia history was from 3 to 20 years,morphology of VT demonstrated right bundle branch block in 4 cases and left bundle branch block in 4 cases,with a rightward axis in 6 cases and a superior axis in 2 cases.Success rate in procedure of catheter ablation was 100% (8/8);Ablation site were located at Left ventricular outflow tract in 2 cases,left ventricular free wall and right inflow tract freewall in 2 cases respectively,left anterobranch bundle near ventricular apex in 2 case.These results suggest catheter ablation for idiopathic ventricular tachycardia of atypical location is highly success rate and the electrocardiography of left ventricular outflow treat VT has special characteristics.
