I don't know - mine was high too!
That looks like my standard winter trace. So I stopped using the HRM part. TMI. I went to ask my doc a couple years ago about this. After 24 hour monitor, stress test and $$$, the Cardio doc - you're healthy! Like almost, why did you bother us. Haven't been back.
The trace shows it high for a few minutes, then down to what I think is an accurate reading. Once sweat occurs on the interface, I think the readings become reliable.
