High AI in paroxysmal atrial fibrillation
Middle AI in paroxysmal atrial fibrillation
Low AI in paroxysmal atrial fibrillation
In this group,patients with paroxysmal AF will receive pulmonary vein vestibule ablation with high AI value, the AI target value for the front wall and the top wall is 550, and the rear wall and the lower wall are 400.
In this group,patients with paroxysmal AF will receive pulmonary vein vestibule ablation with middle AI value, the AI target value for the front wall and the top wall is 500, and the rear wall and the lower wall are 350.
In this group,patients with paroxysmal AF will receive pulmonary vein vestibule ablation with low AI value, the AI target value for the front wall and the top wall is 450, and the rear wall and the lower wall are 300.
