Very high HR readings after exercise

I always wear my HR Chest strap during exercise — After I complete an exercise with the chest strap and complete the activity on my watch (save) I will remove my chest strap. Since the 10.0 update a few minutes after I do this (falling back to the HR monitor on the watch itself) it shows my HR skyrocket — up to the 190-240 range. This morning when that happened, I powered my watch off and back on. The HR was then in the 70s for about a minute, then jumped right back up to 195.

Anyone else seeing something similar? Any Thoughts? I’m thinking there has to be some bugs in the HR algorithms with this code.

I saw the same happen on my 5X+ a few days ago. I removed my chest strap and my heart rate went to 250. I just assumed that the strap had picked up some electrical noise from the surroundings and didn't think more of it.

There was some quite detailed discussion some weeks back about this. It's not related to the most recent update. Have a search through the forum perhaps using 'HRM-Tri' or 'high heart rate' as the search term.

This has happened to me as well a few times. I have resorted to turning off my HRM strap in sensor settings when not in use until a fix is issued.
