Comparison of Pulse Field Ablation and Radiofrequency Ablation in Left Atrial Reverse Remodeling in Patients With Paroxysmal Atrial Fibrillation
The goal of this Ambispective cohort Study is to compare in patients with paroxysmal atrial fibrillation undergo pulse field ablation and radiofrequency ablation, respectively. The main question it aims to answer are:Comparison of the therapeutic effects of pulse field ablation and traditional thermal ablation on patients with paroxysmal atrial fibrillation and postoperative left atrial reverse remodeling.Participants will Perform pulse field ablation or radiofrequency ablation according to different groups, and cooperate to complete outpatient follow-up 6 months after surgery.
• 1.Aged between 18-75 years old; 2.Patients confirmed by electrocardiogram or clinically diagnosed with atrial fibrillation; 3.Atrial fibrillation that terminates spontaneously or through intervention within 7 days after onset; 4.Accompanied by symptoms of atrial fibrillation; 5.The patient has a willingness to undergo catheter ablation treatment; 6.The patient agrees to be enrolled and has high compliance. They voluntarily participate in the trial, sign an informed consent form, and cooperate with the follow-up of this project.
