Caratteristiche elettrofisiologiche dello sviluppo della flessione atriale in pazienti con fibrillazione atriale.

INTRODUCTION: Atrial flutter (AFL) is one of the common atrial tachyarrhythmias concomitant with atrial fibrillation (AF). Few studies have investigated clinical factors associated with the incidence of AFL in AF patients undergoing pulmonary vein isolation. The purpose of this study is to investigate the electrophysiological or structural features of AFL development in patients with AF. METHODS: Patients who underwent AF ablation from October 2023 to May 2024 at Tottori University Hospital were analyzed. Transthoracic echocardiography and computed tomography were performed before AF ablation as structural evaluations in all patients. To assess the electrophysiological features, atrial decr
