Has anyone tried a daily prophylactic dose of Metroprolol before bedtime? My cardiologist tells me it "may" help prevent an A-fib episode.

Thank you to those who responded to my question about watchman vs ablation.

I've heard of a few folk who had an adrenergic afib trigger have a BB help them from getting afib.

Does your trigger tend to be adrenergic or vagal (parasympathetic). For more description go to [learn.afibbers.org] and click on "Are there different types of LAF?"

Basically an adrenergic trigger would happen from increased activity. For example, lifting something heavy up ( a friend got afib when going to pack out a deer he killed, up a steep hill). Vagal or parasympathetic triggers happen after exercise, while quiet, after eating or during sleep, generally.

I think the reason a BB can help some of those with sympathetic or adrenergic triggers is it acts like a "governor" on your metabolism, kind of keeping it tamped down.

Thank you, George.
Much appreciated.

I have been on BB's since 2006. Have had three episodes while on BB's...2018/2019. BB kept the rate low, made me less symptomatic and therefore less anxiety. I believe they have helped...(along with sig diet changes)
