Due to breathlessness after ablation I asked my EP about stopping Bisoprolol to see if that was impacting on my asthma, anyway he agreed being as a rate control and not rhythm, but it did not really make a difference.
However, on stopping the Bisoprolol my SHR increased to between 75/80 BPM, this was then followed by my worst day of my heart being out of rhythm which felt like being back in AF, first time since ablation.
I mentioned all this to the arrhythmia nurse who was unconcerned heart rate.
I did not feel right though and after a few days went back the Bisoprolol (2.5mg daily) and SHR now back to 60/65 BPM, and everything has settled down again.
Weird as Bisoprolol is a rate control and not rhythm control, but for me it has controlled both, as I defo felt different the days rate was up to 80+
