摘　　要：目的探讨使用CARTO系统对起源于心室流出道的室早(速)行射频消融术的可行性及疗效.方法 30例起源于心室流出道的患者在CARTO指导下行射频消融术.结果 26例患者室早(速)起源于右心室流出道,2例患者室早起源于左冠窦,2例患者室早(速)起源于心大静脉.所有患者均成功消融,随访过程中1例患者复发室早,室早数少于4 000次/24 h.结论经CARTO系统指导下行导管消融流出道起源室早(速)是安全有效的.Objective To investigate the feasibility and efficacy of CARTO system for guiding catheter ablation of ventricular outflow tract premature beats and tachycardia.Methods Thirty patients with ventricular outflow tract premature beats and tachycardia were performed radiofrequency catheter ablation guided by CARTO.In all 30 cases,the exciting point originated from the right ventricular outflow tract,the left coronary cusp and great cardiac vein were 26,2 and 2 cases,respectively.Results All ablations were successfully performed,but ventricular premature beats less than 4000/24h recurred in one case during follow-up.Conclusions Catheter ablation guided by CARTO was safe and efficiency for ventricular outflow tract premature beats and tachycardia.
