Hi "delcasa",
Besides my controlled PC, I have (mild) Afib as well. And blood thinners caused an allergic reaction. The Afib got to the point of having ablation to the atrium which has worked perfectly for almost a whole year. My cardiologist says if I have any more Afib we'll look at the "watchman" implant to the heart.
I don't know if either of those would work for you but always worth a chat with both doctor teams.
Bests of luck and keep up the good work.
