I monitor bpm with Kardia. On a single 1 minute occasion it will constantly flip between mostly 50 - 74 bpm but also goes up as far as 130 bpm. However it will often at the end of the minute give a final reading around the high sixties to early seventies which to me appears to be an average.
This is whilst I am experiencing quite severe symptoms of AFib (pain in back/chest, shortness of breath/lightheaded etc.) my conundrum is do I take my Nebivolol in these circumstances when my bpm May be quite low (or not?) or could the Kardia be faulty?
