With my current recurrence of AF, my heart rate hasn't got above 120 as it is controlled by Bisoprolol. Mostly it's in the 80s or 90s. I kept a BP and pulse diary for a couple of weeks. At the beginning, I was still getting pulses in the 50s and 60s and my consultant said I couldn't be getting AF at that level. Still trying to work out what the triggers are for me (probably stress) but does anyone else suffer with AF at relatively low heart rate levels?
Also, I am able to exercise quite well and reach a pulse rate of 130+, which my consultant was happy about, and it returns to normal without triggering AF.
