摘　　要：目的为了探讨射频消融术对频发室性早搏与室性心动过速的疗效。方法观察并随访１０例经ＲＦＣＡ治疗的室性早搏患者；对２例多源性室性早搏患者作了术前心室起源点的多普勒组织成像（ＤＴＩ）检测。结果消融成功７例，失败２例，复发１例；ＤＴＩ检测２例，心室起源点与术中电生理心内导管标测相吻合。结论ＲＦＣＡ是目前值得启用的治疗频发室性早搏伴ＶＴ的新方法，但冠心病人成功率可能偏低；ＤＴＩ作为非创伤性标测起源点，有较好的探讨前景。Objective: To evaluate the treatment effect of radiofrequency catheter ablation (RFCA) in frequent ventricular premature (VP)and ventricular tachycardia (VT). Methods: Ten patients with VP or/and VT were observed and followed-up,ventric- ular origin spots were detected by Doppler tissue imagimg (DTT) in two cases with multifocal Vp among ten cases before PFCA. Results: The result demonstrated that seven cases succeed, two cases failed, one case recured in ten cases after RFCA. Ventricular origin spots in two cases were detected by DTI before RFCA as well as intracardiac electrophysiological measures,in RFCA. Conclusion: RFCA is a new technigue used for treating frequent VP or/and VT presently, but succeed,rate is lower properly in coronary heart disease. It is agood prospect to DTI for researching noninvasive, measured origin spots.
