I have a Fitbit Charge 6.
It's enormously annoying in a number of ways that I have beaten into submission or overcome by strength and wisdom.
But one phenomenon perplexes me: Why does the watch sometimes report much *higher* pulse rates than are actually occurring?
For example, the watch may report 112, when my Kardia monitor and my own finger-on-wrist suggest the number is 60.
I can understand the oft-seen phenomenon of the Fitbit reporting 60 when I'm having afib-120, but the opposite problem baffles me. I have waited several weeks to post this, but now believe that I'm not crazy.
