You are in good hands at Mayo. I am 80-year-old female. I presented with persistent Afib with rvr in March of 2023 and was referred to the Mayo hear rhythm clinic by my cardiologist in the HCM clinic at Mayo. At my consult with the EP in the heart rhythm clinic I was offered either antiarrhythmic meds or ablation (already tried rate control which didn't work). I asked which he recommended and he said meds as ablation is irreversible. So, I went with Dofetilide (Tikosyn) which took a three day stay in hospital to be "loaded," So have now been in sinus rhythm for 13 months except for one 7 day breakthrough which self converted. Good luck.
