17例预激综合症共17条房室旁路(其中左侧12条、右侧5条)行射频消蚀术。2例并有房室结双径路。12例左侧分路和1例右侧旁路消蚀成功(成功率77％)。1例随访6个月时心动过速复发(1／13)。第二次消蚀后出现3°房室阻滞。射频消蚀旁路是治疗房室折返性心动过速的有效方法．今后应加强对右侧旁路消蚀的研究。
17 cases of Wolff-Parkinson’s syndrome with a total of 17 atrioventricular bypass (including the left 12, right 5) RF ablation. 2 cases and atrioventricular node dual path. 12 cases of left bypass and 1 case of right bypass erosion successfully (77% success rate). One patient was followed up for 6 months with recurrent tachycardia (1/13). After the second erosion 3 ° atrioventricular block. Radiofrequency ablation bypass is an effective method of treatment of atrioventricular reentrant tachycardia. The future should be strengthened on the right side of the bypass erosion research.
