摘　　要：目的　提高体表心电图对显性旁道定位的准确性 ,缩短射频消融术的手术时间。方法　对 5 0例右侧显性旁道在射频消融术前采集了头胸导联与常规Wilson右胸导联体表心电图 ,结合射频消融术的靶点进行分析 ,比较其两两的符合率。结果　右前间隔、右前游离壁、右后游离壁及右后间隔的符合率分别为 10 0 %、10 0 %、95 45 %和 90 91% ,常规导联的符合率为 5 8 3 3 % ,68 75 % ,61 90 % ,81 81%。头胸导联对右后间隔显性旁道的定位与常规Wilson导联差异无显著性意义 (P >0 .0 5 ) ,而对右侧游离壁及右前间隔显性旁道的定位诊断明显优于常规Wilson导联 (P <0 .0 1)。Objective To increase the precision in localization of atrioventricular accessory pathway by body surface ECG and to shorten the operation time of RFCA. Methods The features of the body surface ECGs with HC lead and Wilson′s lead were studied in 50 cases of right atrioventricular accessory pathway before RFCA and compared these ECGs for localization of the target point for RFCA. Results The results showed that there was no significant difference in the localization of right-posteroseptal accessory pathway between HC lead and Wilson lead (P>0.05), and HC lead ECG was more useful than Wilson lead when applied to localize the right free wall and right-anteroseptal accessory pathway (P<0.01). Conclusion HC lead ECG is helpful to localize the right lateral accessory pathway precisely.
