Heart Rate Bug, Rapid rise

Since version 4.19 I have the following heart rate problem every other run. The watch always sits snugly and correctly on the wrist.

Anyone have similar problems?

All,

Thank you so much for your patience as we've worked on improvements regarding erratic HR data (sudden drops/spikes) during for certain activity profiles. I deeply apologize for the understandable…

Yes. I’m also experiencing the same issue and would love to be contacted/included in the report in an effort to get this resolved.

Yes

Since firmware 16.x I have issues with spiking or excessive high heart rate. Up to 201 altough my max hr is 186.

Also the max hr auto detection is not working any longer. It comes up with values around…

Since a few days, I'm having this exact same issue. I'm including two graphs as an example.

In the first one, my HR shot up to 201 bpm. I had to stop the activity, take the watch off for a few…

Please see this section from The Heart Rate Sensor on My Garmin Watch Is Not Accurate:

Can you warm-up before you start your next few runs, and let me know if it continues to show a sudden jump?

I am familiar with this site. I already had a vivoactive 3 + 4 and a Venu 2. And with these watches I never had such problems. I will report tomorrow after my run

As you can see, after 4 kilometers of this run, the pulse jumped by a full 20 beats. It was a flat run at a steady pace.

I have compared my last runs and this error appears in all runs from version number 4.19. Before that there were no problems.

This kind of jumps should not happen in the HR detection. Because of this, at any particular moment you just cannot make sure that the measurement has anything to do the actual HR or is it just a guess.

Basically, it makes the reliability of HR values zero all the time.

Instead, if the HR sensor detects anomalies, or environment when it does not have a chance to detect values with a high confidence, it should not guess, it should sign that the confidence level is low at that point, so all the other metrics calculation depending on that can be disabled.

Now, what we have is just a mess of a guesswork in 100% of the time. And a lots of garbage data in all consequent calculation (in stress, TR, RHR, all of them).

dacmic-

Did you try warming up before your most recent example? May I have permission to reach out via email so I can request a few pieces of information?

0 dacmic over 1 year ago in reply to Garmin-Sierra

Yes you can contact me per E-Mail.

I will do 4 Runs this week. After that I can post all data.

Here are 2 more runs. The second a competition, flat. The first is a fast training run with slight inclines.

Only when I'm running at a slow pace, there aren't these jumps in the HR curve.

Hello, was this fixed ? I have the same issue with a brand new forerunner 965. Never happened with my old FR245, kind of regretting the “upgrade” now.

We are still investigating. May I have permission to reach out so I can add you to our report?
