摘要 探讨快-慢型房室结折返性心动过速(AVNRT)射频消融治疗的方法学。7例快-慢型AVNRT患者，在心动过速发作时，寻找慢径最早心房出口作为靶点行射频消融治疗。 6例消融成功。与冠状静脉窦口(CSp)相比，成功靶点A波提前程度平均为9.8±1.3 ms。手术时间87±24 min，X线曝光时间27±12 min，无并发症，随访无1例复发。结论：激动标测寻找最早心房出口点作为消融靶点，是射频消融治疗快-慢型AVNRT安全有效的方法。

Excitation-Mapping to Find the Earliest Atrial Exit of the Slow-Pathway for the Radiofrequency Catheter Ablation of Fast-Slow Atrioventricular nodal Reentrant Tachycardia.

JIN Hua,GUO Ji-hong,XU Yuan,et al.

To investigate the methodology of radiofrequency catheter ablation (RFCA) on fast-slow atrioventricular nodal reentrant tachycardia (AVNRT),the earliest atrial exit of the slow pathway during the tachycardia was selected as the target spot in 7 patients with fast-slow AVNRT,where RFCA was applied.Results: Six of the seven cases were successfully ablated.Comparied with the proximal of coronary vein sinus (CSp),the A wave was 9.8±1.3 ms earlier,with the operation duration 87±24 min and exposure duration to X ray 27±12 min.No complications occurred,nor recurrence during the following up.Conclusion: Mapping the electrical excitation to mark the earliest atrial exit as the target spot of ablation,is a safe and effective method for the RFCA of fast-slow AVNRT.
