Résumé
Background
Pulsed field ablation (PFA) is increasingly used for atrial fibrillation (AF), but device-specific autonomic and respiratory reflex responses remain insufficiently characterized. We aimed to compare vagal responses and cough reflexes among three commercially available PFA systems across individual pulmonary veins and the posterior wall.
Methods
This retrospective single-center study included 200 consecutive patients who underwent AF ablation with FARAPULSE (n = 83), PULSESELECT (n = 83), or VARIPULSE (n = 34). Vagal response was operationally defined as bradyarrhythmia requiring temporary back-up pacing during energy delivery. Cough reflex was assessed intraprocedurally at the left superior pulmonary vein (LSPV), left inferior pulmonary vein (LIPV), right superior pulmonary vein (RSPV), right inferior pulmonary vein (RIPV), and posterior wall.
