Hi everyone. I'm typing this feeling a bit of a fool as I've managed to bring on my second ever prolonged episode of AF, presumably caused by overindulgence of food and drink over Christmas. I had my first prolonged AF episode in July which lasted 30 hours (with an associated very high HR of 160bpm. My resting HR is usually 50.). This was very scary and landed me in hospital. I'm only 39 and had no clue what was going on. They gave me bisoprolol to slow my HR and then the AF seemed to splutter itself into NSR before they'd given me any flecainide or similar (much to the doctor's surprise!). Since then I have had some heart wobbles and flutters and very short (less than 30 minute) episodes which passed on their own. Things were getting progressively better and better. Until last night. I awoke before 3am with very 'wobbly' AF and a HR of 90. It's still going. I feel a bit woozy due to the racing feeling in my chest, but not dizzy or faint. What do I do? Wait it out? I have been on 1.25mg of bisoprolol per day just to help keep my HR low (over-exertion while exercising brought on my first episode). I've just taken my daily dose. Should I just sit out the AF and wait for it to go back to NSR? Or do I need to go to the doctor/hospital? It's been nearly 6 hours now. Thanks, in advance, for any thoughts or comments.
