摘　　要：目的探讨EnSite3000三维标测系统指导下环肺静脉电隔离治疗房性心律失常的临床效果。方法对64例房性心律失常患者(持续性房颤6例、阵发性房颤50例、房速8例),在三维标测系统(EnSite3000/Navx系统)指导下行环肺静脉电隔离术,消融的主要终点为肺静脉电位消失。随访3个月,无房性心律失常发生视为成功;虽有房性心律失常但不伴有症状视为有效。结果 46例患者消融成功,成功率为71.8%;有效8例,有效率12.6%。并发症主要包括心包填塞2例、少量心包积液2例、下肢股静脉栓塞1例、股动静脉瘘1例,无死亡病例。结论三维标测系统指导下环肺静脉电隔离是治疗房性心律失常安全、有效的方法。Objective To investigate the efficacy of circumferential pulmonary vein isolation guided by Ensite3000 3D mapping system in patients with atrial arrythmia. Methods Consecutive pa- tients with atrial arrhythmia underwent circumferential pulmonary vein isolation guided by Ensite3000 3D mapping system. Disappearance of pulmonary vein potential was considered as the ablation endpoint. Suc- cess was defined as without atrial tachyarrhythmia after 3 months, as well as asymptomatie atrial tachya- rrhythmia. Results Clinical success achieved 71.8% and the effective rate was 12.6% in 64 patients. Severe complications included 2 cases of pericardial tamponade and 2 cases of mild pericardial effusion, 1 case of femoral embolism and 1 case of arteriovenous fistula. There was no death case. Conclusion Circumferential pulmonary vein isolation guided by Ensite3000 3D mapping system is an effective therapy and safe for patients with atrial arrhythmia.
