目的：探讨慢性心房颤动（房颤）合并长R-R间期（＞1.5s）经导管射频消融术治疗恢复窦性心律后窦房结功能测定情况，了解慢性心房颤动合并长R-R间期患者窦房结功能有无障碍。方法选择15例慢性心房颤动合并长RR间期初次行导管射频消融治疗并恢复窦性心律的心房颤动患者，术后常规行心脏电生理检查测量患者窦房结功能恢复时间及窦房传导时间了解有无窦房结功能障碍，术后行24h动态心电图监测（Holter）有无长R-R间期再发，并对比术前及术后平均心率变化。结果窦房结功能测定结果显示15例患者窦房结功能恢复时间及窦房传导时间均在正常值范围内，且术后Holter均未见长R-R间期情况。结论慢性心房颤动合并长RR间期患者窦房结功能多无异常改变。

Objective To investigate the function measurement situation of sinoatrial node after the radiofrequency ablation surgery for chronic atrial fibrillation (AF) combined with long R-R interval ( > 1.5 s) in order to understand whether there exists sinoatrial function disorders in patients with chronic AF combined with long RR interval. Methods Fifteen patients with chronic AF combined with long RR interval that received radiofrequency ablation treatment for the first time and regained sinus rhythm were selected. The postoperative routine cardiac electrophysiology examination was conducted to measure the patients' sinoatrial node recovery time and sinoatrial conduction time in order to know whether there existed sinoatrial function disorders. The postoperative 24-hour dynamic electrocardiography (Holter) was conducted to determine whether there was long R-R interval recurrence. The change of mean heart rate between before and after the surgery was observed. Results The sinoatrial function measurement results showed that the sinoatrial recovery time and sinoatrial conduction time of all the 15 patients were within normal range, and the postoperative Holter did not find long R-R intervals. Conclusion The sinoatrial node function of patients with chronic atrial fibrillation combined with long R-R interval has no abnormal changes.
