Charge 6 reached a heart rate of 200+

[JamoC]

Just before bed last night, while doing nothing but sitting, my Charge 6 reached 213BPM and stayed in the 200's for about 5min. I did not feel anything, and grabbed my chest strap to try and compare, but did not get to it in time before the pulse returned to normal range. 

Is there anything known at this point about high BPM or issues with Charge 6? 

I run 3-5k a day (not an Olympic pace, but still 5:30 a km). My heart stays between 150bpm 160bpm. 

Before I run off to the doctor, is there anything anyone may know or have experienced, since getting onto the charge 6? 

Cheers

Since everyone seems to hit 213 on the dot I would assume so. I run 3-5k a day (m-f) and my HR never goes above 170. I feel like I would notice it.

I also have been sitting around often and watch the Fitbit heart rate go up and down on its own. Sometimes 140, sometimes 150 for no reason. I have used a pulse oximeter to confirm the error with the Fitbit.

I would recommend not stressing over Fitbit data. I have seen a cardiologist a few times because of these silly things and he said not to trust them, and if they worked he would bought them instead of the hundreds of thousands of dollars worth of equipment.

Yes, I think you are absolutely right. The same thing has happened several times without me having any problems. 
I now ignore these high values ​​and I feel fine.

Thank you, it was very concerning at the time

I've been having a similar problem with my Charge 5, and come here to see if the C6 has fixed it. Apparently not.

In my case I'm getting high (120 to 170) HR readings in some exercise modes - Workout, Yoga, etc. but not Walk mode. I know they're incorrect because I've checked with pulse oximeter and Polar strap. This occurs in minor-medium exercise and afterwards for 20min or so.

I suspect that these incorrect readings stem from an unfortunate sampling rate, combined with my somewhat irregular HR which is presumably worse during exercise. Whatever it is, it doesn't occur for the pulse oximeter or Polar strap.
