摘要
目的:探讨左心房(LA)后部在慢性房颤(AF)中的作用。方法和结果:有27例慢性AF患者入选。在肺静脉隔离后,采用盐水灌注导管施行连接左右肺静脉的消融以实现对LA后部的隔离。LA后部电活动消失、该区域不能被起搏则为成功隔离。根据心动周期长度(CL)的改变和AF的终止确定消融效果。
Aims: To evaluate the contribution of the posterior left atrium(LA) to chronic atrial fibrillation(AF). Methods and results: Twenty-seven patients with chronic-AF were studied. After pulmonary vein(PV) isolation, the posterior-LA was isolated by ablation joining the right- and left-PVs using an irrigated-tip catheter. Isolation was demonstrated by absent/dissociated posterior-LA activity and the inability to pace the region. Ablation impact was determined by the effect on cycle length(CL) and AF termination...
