My heart rate has always been kind of low, and I'd often catch it in the 50's, especially when laying down. Recently I've become a little worried about it, having measured it at only 50bpm earlier on.
I've read that AF can sometimes manifest as a slow heart rate, but I don't know whether this is rare or not. Does anyone else have a low resting heart rate (normally between 50-65 whilst laying down)?
I should also note that I am awaiting results from a 48-hour heart monitor, and that I take Propranolol as a pill in the pocket measure. However, I have been taking Propranolol pretty much every day, a fairly low dose at 10mg, and is not the slow release pill, so I am unsure whether its efficacy would continue over the course of several hours.
