That's interesting- one time after a max effort up a hill, had 200 bpm reading going down the other side, but didn't feel anything un-ordinary physically.
Max observed at that time was maybe 175. Commenting to the group, a petite woman said maybe I had picked up a reading from her HRM.
Only happened that once, & was concerned but after some years (& plenty of hard efforts) there's been nothing else like it.
