Hi, I've been put on 2.5mg Bisoprolol twice daily for some tachycardia that came up on an 48 hr ECG just over a week ago, as well as several other BP meds to lower my BP which was very high, been on those for 7 weeks.
I understand that the whole point of the Bisoprolol is to lower my Heart rate at it has been hovering in the 41-45 region on most days since I started it, however my Apple Watch just warned me it was too low and I checked on my BP monitor and it was 38. Does this justify a call to NHS Direct, Saturday evening so no GP? I am a a tad worried although I feel fine, BP is normal 125/77? Is this normal on beta blockers? Am due to take another 2.5mg tonight.
