摘　　要：目的观察心房颤动(房颤)患者在EnSite3000指导下射频消融的疗效及安全性。方法回顾性分析2008年3月～2010年12月期间30例房颤患者,其中阵发性房颤26例,合并房早、房速和?或房扑的12例;持续性房颤4例,在EnSite3000指导下进行射频消融治疗。结果 30例患者中22例(73.3%)为1次手术成功;4例阵发性房颤患者在手术6月后未再出现房颤,但反复发作阵发性房扑和/或房速,其中1例因发作频繁于术后半年再次接受射频消融治疗,术后未再复发,余3例患者继续服药观察;4例持续性房颤患者中有2例于术后3～6月内转复为窦性心律,但1年随访时心电图检查考虑为左房房扑,其余2例一直未能转复。共发生2例并发症(6.67%)。结论 EnSite 3000三维标测技术通过构建心脏三维模型,立体直观展示了心脏结构,并可直观显示心律失常起源点、激动顺序及关键部位,提高了房颤消融术的成功率及安全性。Objective To investigate the effectiveness and safety of transcatheter radiofrequency ablation guided by EnSite3000 for the treatment of atrial fibrillation.Methods From March 2008 to December 2010,30 hospitalized inpatients,including 26 patients with paroxysmal atrial fibrillation and 4 patients with persistent or permanent atrial fibrillation suffered from ablation.Radiofrequency ablation for arrhythmias was performed under the guidance of an EnSite3 000/NavX or Array mapping system.Results Successful ablation of arrhythmias was obtained by single operation in 22 cases（73.3%）.4 cases with paroxysmal atrial fibrillation occur atrial flutter or erbiltatrial tachycardia after operation.Ablation procedure was carried out and was successful in 1 case with paroxysmal atrial fibrillation.4 cases with persistent or permanent atrial fibrillation can not restore sinus rhythm operation.After operation,complications occurred in 2 cases.Conclusion EnSite3000 can clearly and stereoscopically display the cardiac structures.Therefore,this technique is of great value in guiding the radiofrequency ablation for atrial fibrillation and in improving the success rate of ablation and in increasing the safety of the procedure.
