I was diagnosed with atrial fibrillation in January, and was put on 2.5mg Bisprolol a day. I started reading as much as I could about the condition, including this forum.
The effects of the medicine were breathlessness, sometimes bad, including a couple of funny turns while I was out and about, weird flutterings in my abdomen just below my ribcage, chronic sleeplessness: I was ticking over on about an hour of catnaps a day. I dreaded going to bed because I knew what a performance it would be. Worst of all was the overall complete and utter lack of interest in everything: I spent my time in front of the television in some kind of suspended animation.
After three weeks I went back to the doctor and said that I was not having this, that I would rather take my chances with no beta blockers than carry on as I was. He said that for the symptoms I described people were usually on 8-10mg a day. So, to make sure there was no misunderstanding, I told him that I would not, under any circumstances, take that high a dose. So he reconsidered, and thought of taking me off beta blockers, which sounded good to me, but then decided to try a lower dose, 1.25mg a day.
This took a couple of days to work, then I couldn't beieve the difference. I felt like I'd woken up from hibernation; all the things I'd moaned about to the doctor had gone, except for the breathlessness, and that was a lot easier. I felt good, about the same as I'd felt in my pre-atrial fibrillation days.
I've since been told by another doctor at the same practise that it is now accepted that lower doses can be more effective than higher ones. At one time everyone had high doses, but now it's accepted that smaller ones can be better. It certainly seems to be the case with me.
Could be worth a try.
Don't lose heart (please excuse the pun).
