Faulty Heart rate.

I am having a garmin forerunner 735xt watch. All working absolutely fine. Only thing is that in running after 2-3 kms the HR suddenly shoots up which is highly unrealistic. I was told to update the software to 9.50 but I am not finding any updates online nor any notification from my watch regarding the updates. The watch shows its up to date. Any solution for this faulty Heart rate issue....?

    It's not a firmware issue. My watch works fine, and I'm running 9.40. Firmware 9.50 is for APAC devices only, AFAIK, and it did not contain any HR-related fixes anyway.

    I am experiencing similar problem. My HR has always recorded a resting rate of 46-47 then for the last three days it has been showing numbers in the high 70’s. does anyone know the cause or have a solution?

    I'm having same problem: heart rate instatntly jumps up to unrealistic values during workout (running) After while it junps back to realistic values. 
    This is my 2nd 735XT with this problem, I'm using a Garmin HRM heart rate band.

    Hi, I have had problems with super high reading popping up out of nowhere, for minutes or longer before normalizing again. The solution was a new strap, all problems disappeared when I switched strap. First I tried switching the heart rate unit on the strap, that didn’t solve it. My guess is that I didn’t wash / cleaned the strap regularly enough, and that caused the wrong erratic readings I got. So I hope this is the solution for this other users who experience the same problems. Keep on running Runner‍♂️
