复发性房性心动过速，后环肺静脉消融房颤：有什么区别？
Recurrent atrial tachycardia and atrial fibrillation after circumferential pulmonary vein ablation: What's the difference?
目的探讨心房颤动（简称房颤）环肺静脉消融术（CPVA）后复发的预测因素。
Objective To determine the predictors of recurrence of atrial tachyarrhythmias(ATa) after circumferential pulmonary vein ablation (CPVA) for patients with atrial fibrillation(AF).
对于阵发性房颤采用环肺静脉消融术式即有良好效果，而对单纯环肺静脉消融不成功者结合节段性肺静脉消融及碎裂电位消融可进一步提高成功率。
Circumferential pulmonary vein ablation alone is enough for paroxysmal AF treatment, while it combined with segmental pulmonary vein ablation and CFAEs ablation may result in high successful rates.
结论：三维标测系统指引导管环肺静脉线性消融治疗阵发性心房颤动疗效高，安全性好。
Conclusion: Circumferential pulmonary vein linear ablation guided by 3d mapping system (CARTO system) was safe and effective for paroxysmal atrial fibrillation therapy.
结论三维标测系统指导下环肺静脉线性消融治疗慢性房颤疗效较好，安全性有待进一步提高。
Conclusion CPVA guided by 3-d mapping system can be performed in CAF patients with an acceptable efficacy, but safety need to be improved.
目的探讨三维标测系统指导下行心房颤动(房颤)环肺静脉线性消融的安全性和有效性。
Objective To investigate the safety and efficacy of circumferential pulmonary vein linear ablation guided by 3-d mapping system in patients with atrial fibrillation.
结论：测量肺静脉电位延迟程度，可用来快速寻找左侧环肺静脉线残余传导裂隙指导补充消融。
Conclusion: the measurement of pulmonary vein potential delay time can be used to quickly find gaps of the left pulmonary vein conduction and supplementary guide ablation.
目的探讨三维标测系统指导下环肺静脉线性消融治疗慢性心房颤动(房颤)的疗效和安全性。
Objective To investigate the efficacy and safety of circumferential pulmonary vein (PV) linear ablation (CPVA) guided by 3-d mapping system in patients with chronic atrial fibrillation (CAF).
目的探讨三维标测系统指导下环肺静脉线性消融治疗慢性心房颤动(房颤)的疗效和安全性。
