About fourteen days ago I started taking Bisoprolol. I had no previous AF problems though I have been on other hypertension medicines which for various reasons I now no longer take. (I could regale you with the eight years of complications caused by the likes of Perindopril and Amlodipine but maybe that's for another time.)
The Bisoprolol was an attempt to help with the blood pressure issue.
However, yesterday I found myself in A&E with an irregular heart beat. After a lot of tests and x-rays and all the usual stuff that goes on the hospital said that yes my heart rate was irregular and the best treatment was to increase the dosage of the Bisoprolol to 2.5mg. They also insisted I take anticoagulants to prevent a stroke. Fortunately my GP was more relaxed about this and suggested we hold fire to see if the heartbeat settles down.
Imagine my horror when last night I read the NHS leaflet on the medicine and it outlined one serious (though rare) side effect was "might cause irregular heartbeat".
Other symptoms which I now realise might be related are headache and upset stomach.
My problem is that nowhere can I find what to do if this side affect occurs. My gut reaction is that I should stop taking the stuff. However, my GP thinks this could cause me to go into rapid A.F. which raises the stakes obviously.
So what to do?
To me it seems bazaar to increase the cause of the problem - As I said no previous AF incidents.
