So sorry to hear of your troubling issues.
One recommendation that has helped me dealing with overall AFiB/stroke issues: the common sense guidance and information on dealing with AFiB long-term in a 2021 book: The Afib Cure by Drs. Day and Bunch. Just finished it and found it very helpful as to real options most all have in dealing with AFiB-- short and long-term.
All the best.
