Hi I suffer from PAF and was prescribed isosorbide mononitrate for angina in January which came on during an attack .
I also take 2.5 mg bisoprolol morning and night which I have been taking for 4 years.
I think the isosorbide is causing an increase I ectopic beats, tiredness and fluid retention. I also have had 3 episodes of AF the past 6 weeks resulting in visits to A ans E . I am wondering if this could be the isosorbide . Does anyone have these side effects .
