摘　　要：目的探讨Ebstein畸形合并右侧旁道的射频导管消融（下称消融）手术方法。方法选择我院26例Ebstein畸形合并右侧旁道的患者行心内电生理检查确定旁道最佳消融靶点，适当增加射频能量和消融时间以到达消融目的。结果26例Ebstein畸形合并右侧旁道的患者，成功消融23例患者共26条旁道。结论选择Webster-7F蓝把加硬Lab导管经右股静脉置于右心房三尖瓣环附近行精细标测。当Lab电图呈现小A大V波且A—V波群融合时，为最佳消融靶点。精标三尖瓣环附近最早心室点、增加射频能量是治疗Ebstein畸形并房室折返性心动过速安全、有效的方法。Objective To investigate means of radiofrequency catheter ablation （RFCA） of right atrioventricular accessory pathway with Ebstein＇s anomaly. Methods The optimal ablation site was determined during electrophysiological test and adequate ablation energy and ablation time were adopted to ablate right accessory pathway in 26 patients with Ebstein＇s anomaly. Results 26 atrioventricular accessory pathways were ablated successfully in 23 patients. Conclusion Careful mapping with a 7 French ablation catheter along the tricuspid annulus to identify the earliest ventricular activation site and adequate ablation energy are required for safe and effective treatment of atrioventricular reentrant tachycardia with Ebstein＇s anomaly：
