About

This study is aimed to evaluate the Efficacy and Safety of Pulsed Field Ablation (PFA) in Patients with Paroxysmal Atrial Fibrillation (PAF)

Full description

This clinical trial is a prospective, multi-center and single-arm Study. It will be carried out in 3 or more clinical trial institutions, and eligible patients with paroxysmal atrial fibrillation are enrolled. For those patients recruited, pulmonary vein isolation will be performed using pulsed field ablation device (Sichuan Jinjiang Electronic Technology Co., Ltd. Chengdu, China). The safety and efficacy of pulsed field ablation(PFA) in Patients with Paroxysmal Atrial Fibrillation (PAF) will be studied using ring-shaped pulsed field ablation catheter
