abnormal high heartrate during activity

8828837

Lately i'm experiencing abnormal hearrates.

I'm running with my dog, the pace drops in the beginning are normal (pee stops from dog :) )

Point 1 is an abnormal peak of +30. I know my body well enough. These reads are wrong.

At point to I was fed up with high heartrate so i took of my watch for a few seconds.

Hearrate was reset and never went to the real level.

Not sure what the watch is showing here but it's certainly not my hearrate.

    How was your running cadence?

    I had the same. Did an easy 12k run with HR around 145 and suddenly it raised to 192 and stayed there for some minutes. I also removed my watch for it to reset. At that point it read 72 for the rest of the run, until in the last 3k cooldown it suddenly moved to 152, which seems correct again. Don’t know what it is, but very frustrating…

    I get this often with HIIT/cardio sessions. I've just ordered a chest HRM because it's clearly not working accurately,  Once in a while I've had this happen with a run but not so often.

    Running cadance.
    no fluctuations that could explaing the jump

    I was just wondering if the cadence was equal to the heart rate, or indicated heart rate. This is a general issue with wrist heart rate sensors, that they pick up the cadence. The algorithms try to filter it out, and can differ from version to version of the software.

    I have a different problem my heart rate drops from a push 160 to 80 and then stays around there for the remainder of the run...

    I also am getting anomalous low heartrates.  It's nothing to do with cadence or anything I change, I can be running steadily with the watch showing 80 or 90 bpm, then it will suddenly jump to a realistic 150 or 160.  Or the jump can happen in the opposite direction.  It can happen at the start of a run, or randomly in the middle.  Takes away the point of the wrist HRM if it only gives true values sometimes

    It makes sense that the heart rate becomes double or half what it was. That is always a strong component when trying to guess the frequency of a noisy signal. The watch will be reluctant to do the jump, as it knows you can not change heart rate that quickly, but the algorithm thinks the new value is more likely based on the activity you are doing.

    Yes that would make sense, but it isn't what is happening.  The jumps are typically from around 90 bpm to around 140 bpm, but can be from around 80 or 90 to anything from 120 to 160.  It is as though the watch is recording the variation in heartrate but missing some, then suddenly making contact.
