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

I agree it happens like once a month of exactly 213 out of the blue for
a few minutes yet there is no irregular heart notice or high heart rate
notice

Same thing here. HR shows 213 while at rest. No symptoms. Seems inaccurate.

Something going on with Fitbit
