连续进行射频消融的355例有症状房室旁路病人中,6例有 Ebstein 畸形。2例有1条旁路,3例有2条旁路,1例有4条旁路。所有旁路均在心脏右侧(后间隔4条,后部4条,后侧2条,前侧1条,前间隔1条);10条旁路为显性,2条为隐性.使用消融导管对旁路进行标测定位,3例加用了心表走行的右冠状动脉内标测.头2例病人消融失败,但后4例病人的9条旁路全部消融成功。射频电流放电次数在位于后区的7条旁路消融时高于位于前区的2条旁路(18±13比6±3,P< Of the 355 symptomatic atrioventricular bypass patients who underwent continuous radiofrequency ablation, 6 had Ebstein’s deformity. Two patients had one bypass, three had two bypass, and one had four bypass. All bypasses were on the right side of the heart (4 posterior, 4 posterior, 2 posterior, 1 posterior, 1 posterior); 10 bypasses were dominant and 2 were recessive. Ablation of the catheter positioning mapping of the bypass, 3 cases with the addition of the left coronary artery within the ambulation of the standard .Above two patients failed to ablation, but the latter four patients all nine bypass successful ablation. The number of RF current discharges was higher at 7 bypass ablations located in the posterior region than at the 2 precordial sites (18 ± 13 vs. 6 ± 3, P <
