PPIs don't affect me personally with AFIB, if fact they seem to help ( my fib is especially affected by Gerd and heartburn ), but, I do know that taking them seem to affect bone health, especially feet.(for over ten years, when taking them daily, I had several fractures in my my feet).
I weened myself off them, and have no fractures since then.
I still take one Aciphex every so often, but not daily.
