Hopefully not tempting fate here but it's been over 6 months now since my last PAF incident. Thing is I have Mi Band fitness tracker which I use to record my HR while sleeping. It appears to be quite accurate when I check my pulse manually against it and recently my HR is down as low as 35 to forty at times while I am asleep. I'm on 1.25 Bisoprolol and 150 Flecainide a day and wonder if anyone else on here has experienced the same or can offer any advice. Thanks.
