How Low will a Fitbit Charge HR record

‎09-24-2020 11:18

Hello,

I am on my 4th Fitbit charge HR over the last 3 years (I am hard on watches). I am very satisfied with it's performance. My question is how low will it record or will it chart lower than 38 BPM? About every third night or so my watch spikes down to 38 and cuts out for about 20 minutes or so. My resting heart rate is usually between 47-51. Will another fitbit model go lower?

I have often several months ago seen sleeping heart rate recording down to 33 with RHR 37 (probably because of an arrhythmia), but it did not cause any discontinuities.  This was with a Versa 2.  Not sure, but I doubt the specific model matters - much of that is handled on back end at Fitbit and in the app.  But I suppose it possibly could be the Fitbit model.

I wonder if perhaps yours slides around on wrist causing the discontinuity. 

Before posting, re-read to see if it would make sense to someone else not looking at your Fitbit or phone.

Are you sure that it is correct, and if so, have you talked to a doctor about this? Bradycardia is something you should check out. I had a RHR that low, and the GP changed my medication. 

 

My Fitbit Charge 2 has a fault where every now and again it tells me my heart rate went up to around 185 for a while. I'm severely disabled and mostly bedbound, so I'm not exercising, and I'm not having regular heart attacks. It's just a Fitbit fault. I use the exercise tracker to show my detailed heart rate for those minutes, then I can subtract the incorrect ones from my actual number of minutes in my peak heart rate zone that day, which I track for health reasons.
