For me the triggers were stress, poor sleep (obstructive apnea), and 2nd martini, with emphasis on stress. I had about a half dozen episodes over 18 months, each lasting a max of 5 hours. I haven't had another episode since my PF ablation in January 2025 (touch wood). Still get occasional palpitations (PVCs, PACs). Currently on 25mg metoprolol, Xarelto and CPAP machine. Considering a Watchman procedure.
