简要总结
The purpose of this study is to verify the safety and efficacy of the cardiac pulse ablation system in paroxysmal atrial fibrillation to provide the basis for product registration and clinical application.
The trial will be conducted at a clinical center with appropriate clinical cases, and paroxysmal atrial fibrillation ablation procedures will be performed by an authorized investigator using the trial product. The effectiveness and safety of the cardiac pulse ablation system in the treatment of paroxysmal atrial fibrillation will be verified by collecting the treatment success rate, immediate ablation success rate, procedure time and device use evaluation within 12 months after the procedure.
