Good luck with your appointment @Brenda5. I am on beta blockers too, a post chemo compounded by age arrhythmia, but I just get a bit racy at times! Or at least used too, been ages since I had any incidence or at least too little to notice. I was on medication, as well as the beta blockers, which stopped working, so my cardiologist suggested beta blockers alone rather than upping the dose (with possible side effects). The irregularity is minor, not constant and gives me no side effects. So far (nearly three years), so good. Hope you get a workable and easy solution to your opinionated heart too.
