目的 :对 10例心动过速病人射频消融术 (RFCA )进行分析。方法 :全部病人行心内电生理检查 ,准确找到靶点后行RFCA。结果 :诊断室速 (VT) 2例 ,房室结折返心动过速 (AVNRT) 2例 ,右侧旁路 (RAP) 1例 ,左侧旁路 (LAP)5例。 7例消融成功无复发 ,1例LAP术后 3月复发 ,2例VT不成功 ,但长期随访比术前状况改善。随访 7月所有病人均无并发症发生 ,效果良好。结论 :准确靶点定位和导管操作技巧是RFCA成功的关键。心动过速类型 ,靶点位置和消融后延迟作用是影响RFCA成功的重要因素。
Objective: To analyze the radiofrequency ablation (RFCA) in 10 patients with tachycardia. Methods: All patients underwent electrophysiological examination, find the target accurately after RFCA. Results: Two cases were diagnosed as ventricular tachycardia (VT), two were AVNRT, one was right bypass (RAP) and five were left bypass (LAP). Seven patients had successful ablation without recurrence, one patient recurred after 3 months of LAP operation and two patients failed VT. However, long-term follow-up improved compared with that before operation. Follow-up in July all patients without complications, the effect is good. Conclusion: Accurate target location and catheter handling techniques are the keys to RFCA success. The type of tachycardia, the location of the target and the post-ablation delay are important factors that influence the success of RFCA.
