hi, all .have been referred back to cardiologist, having ,not sure how to describe , breakthrough beats, irregular ,kind of 3 then miss one. After a couple of days goes back to sinus rhythm (hey getting to grips with these terms!) This has happened quite a bit of late. I'm on Bisoprolol 5mg and 20mg Rivaroxiban. I have controlled mild asthma and do not suffer with high blood pressure. Some of the alternative drugs seem to have awful side affects. thanks everyone. what drugs are you on for something similar?
