Software 19.18. I had been getting nagged into upgraded to 20.x, but I kept postponing it.
So, this past Thursday I did a Bruce Protocol Stress Test with EchoCardiogram (12 leads, technician, periodic BP checks, the whole nine yards).
To my credit, I lasted 15 minutes, but that's beside the point.
The technician said my heart rate was 190 at the end.
While I didn't start an activity on my watch, it apparently auto-detected a cycling activity.
I checked my watch and found my heart rate was nowhere near 190. Not even close. See attachment.
How can it be so wrong? Is it ever right?
