射频消融治疗多条折返径路的心动过速12例

目的 总结实用而有效的常规消融方法。方法 回顾分析了12例具有多条折返径路的心动过速病例的电生理检查结果，总结了其消融操作流程。结果 12例中，同时具有三条房室旁路1例，两条房室旁路者7例，一条房室旁路伴房室结多径路者2例，房室结三径路者2例。共计消融慢径2条、旁路19条（包括左侧旁路7条、右侧旁路12条，其中显性旁路10条，隐匿性旁路9条）。结论 消融前后详细，标准的心内电生理检查可提高多折返径路心动过速的检出率。

Radiofrequency ablation of 12 tachyarrhythmias with multiple reentrant pathways

Objective To draw the routine and effective method about radiofrequency current catheter ablation.Methods Analysed electrophysiology treat of 12 cases tachyarrhythmias with multiple reentrant pathways,we indicated the operation routine of catheter ablation on these cases.Results In 12 cases,there was 1 case with three atrioventricular accessory pathways(AP),there were 7 cases with two AP,there were 2 cases with one AP and multiple atrioventricular nodal pathways at the same time,there were 2 cases with three pathway in atrioventricular node.We ablated 2 slow atrioventricular nodal pathways and 19 AP in 12 cases,It include 10 manifest AP and 9 concealed AP,7 left AP and 12 right AP.Conclusion It is necessary to perform detail and standard electrophysiological test before and after ablation to find out multiple reentrant pathways.
