I have been well controlled on Bisoprolol & Flecanide until gastroenteritis sent me into violent AF I spent 24 hours in hospital & my meds were changed. Bisoprolol increased & Flecanide stopped as some VT shown on an ECG in the ambulance. Once home I keep having AF attacks - have seen a cardiologist privately & Bisoprolol increased again to 2.5mg twice a day. Now for last 4 nights I have had AF as soon as I get into bed, it lasts all night but resolves at get up time. I do manage some sleep as it is gentle - heart rate 140. I know this as have an Alivecor. Any one throw any light on this phenomenon. I see the cardiologist in a week & will have a monitor - a small patch type one of American origin. Wish I had it now. I am so apprehensive at bedtime which of course doesn't help.
