Hi. No I haven't asked my cardiologist about changing to another Beta Blocker, although he did admit the metoprolol may cause some hair loss. I kidded with him and said my hair is more important than my health. LOL. Also, hoping the ablation for paroxysmal AFIB will take care of a few other wild and crazy SVT's etc. I have it on June 5. I will post you all about the results and how I'm doing.
