| 摘 要： | 目的探讨对特发性左后分支室性心动过速(简称室速)患者进行射频消融时,同时标测到舒张期电位(diastolic potential,DP)和最早收缩期前P电位(Purkinje potential,PP)作为靶点的消融方法,是否优于以最早PP为消融靶点的方法。方法对18例左后分支室速患者进行电生理检查,根据消融靶点不同分为2组:DP组(同时标测到DP和PP)和PP组(仅标测到最早PP)。以室速不再被诱发作为消融成功终点。比较2种方法的成功率、手术时间、X线曝光时间、消融次数、并发症发生率和复发率。结果18例患者中1例不能诱发室速,未行射频消融。17例诱发出临床室速,表现为右束支阻滞形,电轴左偏,其中DP组7例,PP组10例。所有患者均达消融成功终点。DP和PP距体表QRS波的间期分别为(60.17±8.16)ms和(30.64±7.19)ms。2组患者的年龄、室速的周长、手术时间和复发率无统计学差异(P>0.05)。与PP组相比,DP组X线曝光时间较长(18.33±1.51)minvs(15.37±2.77)min,P=0.03],消融次数较少(4.55±2.07)次vs(7.50±1.64)次,P=0.0...

| Abstract: | Objective To investigate whether taking diastolic potential(DP)and earliest Purkinje potential(PP)as ablation targets together is superior to taking earliest PP alone in patients with left posterior fascicular ventricular tachycardia(VT).MethodsTotally 18 patients who were admitted in our department from May 2006 to May 2009 were enrolled,and the results of their electrophysiological examination were analyzed.According to radiofrequency(RF)ablation targets,patients were classified into 2 groups:DP+PP group(... |
