I'm not the most athletic of people, yet this is not an uncommon sight on my garmin app, and I have confirmed it by manual measurement. Dear lazyweb, should I be asking my doctor about bradycardia?

Thanks to everyone who responded -- For reference, that 42 was while awake, though quite relaxed. In fact, I'm sat at my desk typing this and my pulse is only 51 now. I think, since I'm not overly fatigued/worried, I'll just tack it onto the list of things to ask GP next time.

My record resting bpm is 41 and I can easily drop to 50 by sitting still. GP said if I feel otherwise fine don’t worry about it.
