I have had two incidents where it showed heart rate climbing and climbing and as this triggered anxiety, my panic set in and my heart rate increased further, so I don’t know if it was accurate to start with. Once was during exercise and once at rest.  Looking back at my readings I found a spike to 210 bpm while I was doing a quiet activity a week ago. Do not recall symptoms. It is hard to know if it is malfunctioning or accurate when the spikes occur . 😞

It was accurate against my pulse oxymeter the most recent during the most recent incident tho

This might be an artifact that can happen when the band is too loose.

 my wife's fit bit showing 94, mine showing 69. This was like this for 20 mins. I even reset my fit bit. Mine is the one that spikes, and I can't get an accurate reading. I really don't trust this one.

Was it stuck on 94 for 20 minutes ? Or were the readings on the two watches different for 20 minutes? It is very frustrating because it is accurate for a lot of the time but then malfunctions so one feels like it is not trustworthy . I read that with cycling the hand/wrist motions could interfere (I also cycle indoors)

My last 2 didn't do this. It was fluctuating a few beats from 94 and 69.
