I am in rhythm bp fine.one doctor says to take bisoprosol fumarate if i go back into af. my other doctor says to take it all the time. opinion please?

Depends.: Beta blockers slows your heart rate and lowers your blood pressure. Beta blockers are helpful to lessen your heart rate when you are in afib. They help reduce symptomatic episodes of atrial fibrillation by controlling your heart rate. Bottom line, the more frequent and symptomatic your episodes are, the more it might sense to take it daily. I would base the decision on what minimizes your symptoms

Depends on burden AF: If you are having atrial fibrillation frequently, then taking the bisoprolol regularly will likely reduce this burden. If, however, you get it infrequently, and bisoprolol has historically helped convert you from AF to normal rhythm, it can be utilized as a "pill-in-the-pocket" approach. Alternative would be to assure your flecainide dose is maximized, or switch to alternative antiarrhythmics.
