Methods:We ablated the ventricular tachycardia of 12 patients with normal hearts by the catheter, using pace mapping and activation sequence mapping. The former original target was the site where the pacing QRS was entirely consistent with IVT(Idiopathetic Ventricular Tachycardia) attack. And the latter original target was the site of in advance of earliest high frequency and low amplitude local potential on surface electrocardiogram QRS≥20ms, using activation sequence mapping. Results: Among 12 patients, the IVT originated from right ventricle in 2 patients, from left ventricle in 10 patients.

对12例正常心脏室速进行导管消融，采用起搏标测与激动顺序标测，前者以起搏时与室速QRS波型形态完全相同，后者以激动顺序标测法定位，以记录心动过速时较体表心电图QRS提前≥20ms的最早高频低振幅局部电位处为消融靶点，结果：12例患者室速起源部位分别为：右心室2例，左心室10例，疗效100%。
