目的 探讨射频消融术在心房扑动中的应用。方法 I型心房扑动患者 9例 ,男性 5例 ,女性4例 ,药物治疗疗效不佳而接受射频消融术治疗。结果 9例房扑均为I型房扑 ,8例消融成功 ,1例因年龄较大 ,手术时间较长 ,患者不能耐受而放弃。所有射频消融患者随访 4个月至 2年未发现复发及并发症。结论 折返环在经典的解剖峡部的慢传导区域房扑导管消融成功率高 ,手术风险小 ,值得推广应用。
Objective To investigate the application of radiofrequency ablation in atrial flutter. Methods Nine patients with type I atrial flutter, 5 males and 4 females, were treated with radiofrequency catheter ablation. Results Nine patients with atrial flutter were type I atrial flutter, 8 patients successfully ablated, and one patient was abandoned because of the older age and longer operation time. All radiofrequency ablation patients were followed up for 4 months to 2 years, no recurrence and complications were found. Conclusion Reentrant ring in the classic anatomical isthmus slow conduction area atrial catheter ablation success rate is high, the surgical risk is small, it is worth to promote the application.
