This is a prospective clinical study aiming to evaluate the clinical efficacy and safety of a novel domestic pulsed field ablation (PFA) system in the treatment of paroxysmal atrial fibrillation (PAF), and to specifically assess its protective effect on left atrial function. Approximately 200-220 patients with paroxysmal atrial fibrillation are planned to be enrolled. Participants will be treated with the novel PFA system (YTL-PFA01) and a three-dimensional electroanatomical mapping system. The primary objectives include: Efficacy: Immediate pulmonary vein isolation success rate, and freedom from atrial arrhythmias (\>30 seconds) at 12 months post-procedure. Safety: Incidence of major complications (such as cardiac tamponade, stroke, pulmonary vein stenosis, phrenic nerve palsy). Left Atrial Function: Dynamic changes in echocardiographic parameters (e.g., LAVI, LVEF, E/A, LASr/cd/ct) and serum biomarkers (e.g., troponin, BNP, inflammatory markers) at multiple time points before and after the procedure. Patients will be followed up for 12 months to evaluate the long-term…
