摘　　要：目的探讨CARTO系统指导下三点法导管消融治疗典型房扑的可行性及疗效.方法体表心电图及心内电生理检查证实为典型房扑患者共26例,11例患者行右心房常规激动顺序标测后消融三尖瓣峡部,15例患者三点法消融三尖瓣峡部.术后定期随访及记录症状心电图.结果 2组患者手术成功率及复发率无明显差异;三点法消融组X线曝光时间,手术时间均明显较常规激动顺序标测组短[(72.66±29.82)vs(102.52±32.61)min];[(4.26±2.76)vs(7.32±3.16)min].结论 CARTO系统指导下两点法导管消融治疗典型房扑是安全有效的,并可明显缩短手术时间及X线曝光时间.Objective To evaluate the feasibility and effect of three-points ablation approach in in treatment of typical atrial flutter guided by CARTO. Methods Twenty-six patients with typical atrial flutter diagnosed by ECG and electrophysiological study （EPS） were enrolled in this study. Activation sequence mapping and linear ablation were performed in 11 patients （conventional group） . Three-points guided linear ablation with CARTO system was performed in another15 patients （three-points group） . Results There was no significant difference in the success rate between the two groups. Both the procedure and fluoroscopic time in three-points group were significantly shorter than that in conventional group [（72.66±29.82） vs （102.52±32.61） min;（4.26±2.76） vs （7.32±3.16） min] . Conclusions The three-points ablations approach is as safe and effective as conventional ablation approach in treatment of typical atrial flutter;however,the former can significantly shorten the procedure time and fluoroscopy time.
