Strange HR recording with Burner selected

[Dimitrios Kanellopoulos]

@tonyg do you have a link ? On Strava how does the hr look like?

Was that a belt ?

@dimitrios-kanellopoulos The HR on Strava looks like the chart on SA and as such gives 107bpm Average,

here the link to SA,

Interestingly I have just read on Facebook group a chap with same or similar issue

@tonyg was that a polar h10 ?

[TonyG]

@dimitrios-kanellopoulos yes!

[Dimitrios Kanellopoulos]

@tonyg please share with me in pm the link. I have a possible explanation for this if I am correct.

However I guess this is HRV / RR data issue.

It’s been explained a couple of times and I think if you load the file on QS you will see the same result.

The problem is that when the belt looses good readings RR data are only few creating a low heart rate.

But then I have the question. Did you see on the watch the correct heart rate but only later in the app you have this issue ?

[TonyG]

@dimitrios-kanellopoulos throughout the run I saw good Hr reading on the watch, only once did i see a low hr reading, and that was after pausing the activity to cross the road, when i un-paused it it showed 55hr but very quickly (10 seconds or so) climbed back to 147bpm (where it should have been).
apologies, what link would you like shared?

[Dimitrios Kanellopoulos]

@tonyg pm the link please.

[Dimitrios Kanellopoulos]

@tonyg will be taking a look next week though so take your time.

[TonyG]

@dimitrios-kanellopoulos sorry, not sure what link would you like pm’d

I thought I supplied them all in an earlier post.

I’ve got some weird noise

[Dimitrios Kanellopoulos]

I found the issue.

@dimitrios-kanellopoulos and it is?

[Dimitrios Kanellopoulos]

@egika at some point it looks like the h10 stops broadcasting RR / IBI data (HRV) that we use to create the HR and switches to HR samples and quite a few HRV samples.

It looks like an h10 edge case (both users have the same belt) so I am not sure how this should be fixed

[TonyG]

@dimitrios-kanellopoulos would this be the case for all belts sold and used, I wasnt sure if all belts recorded or broadcast R-R data, so is the watch displaying a different value, as it was displaying the correct Hr Value throughout the activity and I was checking alot due to having this issue on a previous activity.
Is it related to using the burner app? or would a drop in R-R data have this issue regardless.
many thanks for exploring and discovering the issue.

@tonyg not realted to burner. Just your belt stops broadasting RR / HRV and switches to normal HR.
