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.
导管射频肺静脉口环状消融治疗局灶性心房颤动。

结论：电学隔离肺静脉治疗AF是可行的，形成确切的连续透壁肺静脉损伤可简化消融治疗AF的径线。
Conclusion: Pulmonary veins isolation is an feasible treatment for AF. Ablation linear for the treatment of AF can be simplified if continuous and transmural lesion were produced.
结果本组研究总共消融了36条肺静脉，包括16条左上肺静脉，12条右上肺静脉，7条左下肺静脉，1条右下肺静脉。
Results a total of 36 pulmonary veins were ablated, including 16 left superior, 12 right superior, 7 left inferior and 1 right inferior.
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.
目前肺静脉隔离射频消融治疗房颤用于治疗复发性有症状的或对抗心律失常药物不敏感的房颤患者。
At present, pulmonary vein isolation with catheter ablation is an effective treatment in patients with symptomatic atrial fibrillation refractory or intolerant to anti-arrhythmic medications.
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).
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.
本研究提示阵发性房颤患者的首选消融策略为肺静脉前庭隔离术，而不是碎裂电位消融术。
However, no randomized study comparing the clinical efficacy of PV antrum isolation ablation versus CFEs ablation as a primary strategy in patients with paroxysmal AF has been performed.
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.
结论消融右肺静脉脂肪垫使高位右心房房颤诱发率降低及房颤诱发窗口变窄，却使左房、右上肺静脉房颤诱发率升高及房颤诱发窗口增宽。
CONCLUSION RPV fat pad RFA decreases the induction of AF at the HRA, while increases the induction at the left atria and the RSPV.
