摘要
目的观察老年心房颤动（房颤）患者射频消融术后的有效性,探索房颤射频消融复发的危险因素和独立预测因子。方法选取2009年3月~2013年5月在我院心内科首次行房颤射频消融术的老年患者91例,收集临床、电生理及随访资料,分析其长期有效性、复发心律失常类型,探索复发相关指标。结果 91例房颤患者中,单次消融后有效率为58.2%,部分复发患者进行再次射频消融后总体有效率上升为71.4%,左心房容量〉40ml为房颤患者单次射频消融术后复发的独立危险因素（OR=2.569,95%CI：1.072~6.154,P=0.034）。无影响预后的严重围术期并发症。结论对于老年房颤患者,射频消融治疗具有明确疗效且安全性较好,应注意心房扩大患者射频消融治疗后存在更高的房颤复发率。
Objective To study the role of radiofrequency ablation（RFA）in treatment of AF and the risk factors for recurrent AF after RFA in elderly AF patients.Methods The clinical,electrophysiological and follow-up data of 91 elderly AF patients who underwent RFA in our hospital from March 2009 to May 2013 were collected and the long-term effect of RFA,types and related indications of recurrent AF were analyzed.Results The efficiency of a single RFA was 58.2%in the 91 AF patients,the total efficiency of the second RFA was 71.4%in some recurrent AF patients.Atrial enlargement（left atrial volume40ml）was an independent risk factor for recurrent AF after single RFA（OR=2.569,95%CI：1.072-6.154,P=0.034）.No severe complication was found in perioperative period.Conclusion RFA is effective and safe for elderly AF patients.However,the incidence of recurrent AF is high in patients with their atrium enlarged after RFA.
