Heart rate sensor show very high result

Hello,
Got a problem indicated above. Doing cardio shows after about 5 minutes the value above 160 bpm. But after turning and switching on again watches got back to the normal result about 130 bpm. 

But on the running mode seems pretty ok. 
How to get rid of that?

  • I have the same problem during a running activity. With a heart rate strap the rate is ok but running only with optical wrist heart rate shows weird data.

    after a few minutes the heart rate shoots up without raising the pace or intensity.

    Here is an example of an constant run, where heart rate is normally by constant 140 bpm. After approximatly 10 minutes it goes up without a reason for the first time:



    There is no improvement since last updates. This run was made with Software version 8.10 on Marq Expedition.
