I have Hashi's and A Fib. It seems when my TSH is suppressed at 0.01( 0.35-4.94) and my free t3 and free t4 are optimum and I feel really well, that my A Fib is triggered more frequently. I don't know if my TSH is the cause but I have read it can be. I was thinking of changing back to t4 because of this. I didn't feel as well on t4 only so I'm looking for opinions on this. 😏
