预激综合征患者发生心房颤动的危险因素及射频导管消融房室旁路后的远期预后

目的 分析预激综合征伴心房颤动（房颤）患者的危险因素，研究射频导管消融房室旁路对房颤复发的影响。方法 639例行射频消融术的预激综合征患者，对可能发生房颤的危险因素和消融房室旁路后房颤复发的影响因素进行分析。结果 82例(12.8％)有房颤，557例无房颤。预激综合征伴房颤组男性、高龄、多旁路者更多。对成功消融房室旁路...

The risk factors of atrial fibrillation in patients with Woiff-Parkinson-White syndrome and radiofrequency catheter ablation

Objective To analyze the risk factors of atrial fibrillation( AF) in patients with Wolff-Parkinson-White (WPW) syndrome and to explore the possible predictors of AF recurrence after successful ablation. Methods The study population consisted of 639 patients with WPW syndrome underwent radiofrequency catheter ablation. Multiple factors were analyzed to define the risk factors of AF and the predictors for AF recurrence. Results Eighty-two patients (12. 8％ ) had documented ECG of AF. Compared to the patients without AF,there were more men, older, and higher incidence of multiple accessory pathways in patients with AF. In the patients with AF,57 patients were successfully followed up. Six of the 57 patients ( 10. 5％ ) had documented ECG of AF. The possible predictors for AF recurrence were examined. There were more women,older, in patients with recurred AF and more of them were associated with cardiac diseases, larger size of left atrium. Conclusion Male,older age,and multiple accessory pathways are the risk factors of AF in patients with WPW Syndrome. Radiofrequency catheter ablation of accessory pathway can cure WPW syndrome and AF spontaneously in most patients during a long period of follow-up. Female, older age, associated cardiac diseases, longer duration of AF history and larger left atrial diameter may be predictors for the recurrence of AF.
