Heart rate spikes with hrm-pro

HRM Pro spikes and doesn’t drop

This seems to happen randomly when I’m running on the treadmill. Ran intervals and heart rate spiked, ok, but on my recovery run in between heart rate was still going up. At the end, on my recovery I took the hrm-pro off and dropped it on the floor, my heart rate kept going up… reaching over 200bpm. Strange as the hrm-pro wasn’t on…

I don’t believe it’s the cadence issue as you see my image. This is a replacement hrm as I had this issue before. Garmin suggested it was a bad hrm. 

further I’m using the forerunner 965

Any ideas what’s going on here?

    Taking it off doesn't really disconnect it. I find you must manually disconnect it under sensors and accessories menu.  Or strap can still  send  random heart rate to activity while not on your body.  (And get random spikes )
