Heart Rate Monitor is Low

[Amnester17]

I just got a fit bit charge and the heart monitor is constantly reading my resting bpm to be in the 50s, mostly the high 50s. I know this isn't going to be exact and the only reason that I'm worried is because when working out, I have had to stop because I felt like I was going to pass out or I knew that if I even kept standing I was going to blackout. I do have iron deficiency anemia which has causes me to pass out before but that was years ago. So I'm not sure whether I should be concerned about the low ratings and if it is something I should be checking in with a doctor about. Any advice?

I would suggest you speak to you Doctor about this, and the sooner the better.

I would check with your doctor. There are two completely different issues here. The first is your resting HR which is actually normal. Mine is slightly lower than that. The second, feeling like you are going to pass out during a work out, indicates an HR that is too high.. I would make an appt.

I'd definitely recommend you to visit your doctor and tell them how you feel since it is very dangerous that you feel like passing out.
