Wrong heart rate measurement

I’ve noted that when I run, after some kms , the heart rate rate showed is not correct.

it jumps from 165 bpm to 210(!), even if the pace and gradient maintains de same.

I’m sending one example where by the end of the effort I’ve increased the pace and the heart rate, decreased to 165 (that I think it was finally correct) from 213…

What can be done to fix this ?

Please see my most recent comment regarding this on Heart Rate Bug - Part 2. There's a new thread for anyone having HR issues after downloading 18.20: 18.20 HR bug still here.

Might be a cadence lock - which sometimes happens when our devices are moving around a little too much on the wrist (try tightening the strap a notch and see if that helps).

I have the same issue with such a bug. Previous thread was closed from Garmin. They are investigating the core or root cause but on the other side we can’t rely on such a premium device as FR965 is. This is causing lots of issues - mostly with recovery time when HR is measured wrongly with lots of peak which are exceeded HR MAX.

Dear Garmin team do you have some news regarding this topic?

I have the exact same issue with the heart rate monitoring from the wrist. It started suddenly at the end of december 2023. I tried to solve this by tightening and loosening the wrist band and placing it higher and lower on the wrist. Nothing helped. Now I'm wearing a chest strap as a temporary solution. Could this be fixed by a software update?
