研究目的:

1.主要目的:通过对比单圈隔离率,研究半浓度生理盐水灌注下的超高效消融模式在房颤环肺静脉隔离中的有效性; 2.次要目的:通过对比pop的发生率,研究半浓度生理盐水灌注下的超高效消融模式在房颤环肺静脉隔离中的安全性  

Objectives of Study:

1. Primary Objective To evaluate the effectiveness of a very-high-power, short-duration ablation mode with half-normal saline irrigation, as measured by the single-procedure isolation rate, in patients undergoing pulmonary vein isolation for atrial fibrillation, compared to a conventional ablation mode. 2. Secondary Objective To evaluate the safety of a very-high-power, short-duration ablation mode with half-normal saline irrigation, as measured by the incidence of cardiac tamponade/perforation, in patients undergoing pulmonary vein isolation for atrial fibrillation, compared to a conventional ablation mode.
