<bot>: Hello. Thank you for asking on Chat Doctor. There are many alternatives on treating, maintaining and controlling the atrial fibrillation. If you do not have airway or lung problems, I would recommend Atenolol 50 mg x 2/d (or metoprolol), which is a beta-blocker with a stronger effect on heart beat, than bisoprolol. You can also consult your cardiologist on switching to treatment with digoxin or a calcium channel blocker, such as verapamil or diltiazem. I hope I was helpful. Take care. Good day
