目的总结射频消融术(RFCA)治疗快速性心律失常的经验教训。方法回顾性分析RFCA治疗48例快速性心律失常的结果,其中房室结双径路16例,预激旁路20例,双径路合并旁路2例,特发性室性心动过速5例,心房扑动5例。结果RFCA治疗快速性心律失常成功率97.7%(47/48),复发率4.2%(2/47),均再次消融成功,1例转为心房纤颤未再消融。1例Ⅲ度房室传导阻滞留观18天后转复为窦性心律,术中3例发生血管迷走反应,均对症处理缓解,无心包填塞、血胸、气胸等严重并发症发生。结论RFCA是治疗快速性心律失常安全有效的根治性方法。
Objective To summarize the experience of radiofrequency ablation (RFCA) in the treatment of tachyarrhythmia. Methods A retrospective analysis of RFCA treatment of 48 patients with tachyarrhythmia results, including atrioventricular node dual pathways in 16 cases, pre-excitation bypass in 20 cases, dual-path bypass shunt in 2 cases, idiopathic ventricular tachycardia in 5 cases, Atrial flutter in 5 cases. Results The success rate of RFCA in treating tachyarrhythmia was 97.7% (47/48) and the recurrence rate was 4.2% (2/47). Both of them were ablated again and one case had no further ablation of atrial fibrillation. A case of Ⅲ degree atrioventricular block observed 18 days after the turn into sinus rhythm, 3 cases of vascular vasoconstriction occurred, were symptomatic relief, no cardiac tamponade, hemothorax, pneumothorax and other serious complications. Conclusion RFCA is a safe and effective radical treatment of tachyarrhythmia.
