Hi vyronp: I had a DVT and they found AFib going on. Started me out on 25mg of Metoprolol. 2 x a day. I was a slug. I kept cutting down. I still take 1/2 of a 25mg once a day. But now a new Dr has decided that my heart was beating so slow as to not keep the fluid build up down. So I'm asking like you, why keep the Metorpolol. I also have never had high blood pressure. Right now it's 122/84/heart 74.
