HRV app. Discussion, report bugs, suggested features, etc...

HRV
Get the app.

Graphing.
The design currently only saves to 1 location per day. The timestamp is taken when the test starts, so autostart will take the timestamp at the scheduled time. This means that any saved test will overwrite any previous test of that same day. A day is calculated from the local timezone, so travelling won't disrupt the storage so long as you have updated the timezone before starting the test. The averages are a 30 day mean average.

Description & Explanation
Wouldn't that be nice. Will happen, but might take a while.
This page could be useful.

Notes
- Your device must have firmware that supports Connect IQ Apps.
- You can save the results by creating a log file. To do this you must work out which name has been applied to the HRV app file. The apps are in the /GARMIN/APPS folder. It will be a name something like A6227C9B.PRG. You then create a log file with the same name, e.g /GARMIN/APPS/LOGS/A6227C9B.TXT. Each reading you save will output a result formatted as ISO8601 date & time, hrv, avg pulse, 30 day hrv avg, 30 day pulse avg.

Fenix 3 HR and HRV app

I just bought a new Fenix 3 HR with the sole purpose of evaluating it's ability to measure heart rate variability but the app doesn't work.

Running 2.2 software.

Anyone else with the same issue?

It seems someone's already tested that out and the outcome was that "r-r" intervals on Garmin's Elevate sensor are just too inaccurate unfortunately -> https://forums.garmin.com/showthread.php?219097-Watch-App-HRV&p=821840#post821840

I would just like to say that your requests are not going unnoticed. This project is not currently active, but neither is it forgotten.

I am a physician who specializes in measuring HRV and other autonomic measures routinely in my clinical practice. HRV is most greatly reflected in the parasympathetic branch of the autonomic nervous system and is what clinicians refer to when stating HF (high frequency).

LF (low frequency) represents the sympathetic branch.

Parasympathetics can be measured a variety of ways but rMSSD combined with paced breathing seems to be the most consistent method in portable devices. The sympathetics are more difficult to measure reliably.

Hope that helps.

It does help thanks!
So, in your opinion I should do paced breathing while measuring the rMSSD?

Timer setting ?

Hi,

Sorry for my bad english ... I'm french.

How can we set the timer with another value (default = 1') ?

RMSSD test should usually be performed on at least 5 ' no ?

Thanks

You can set the timer for any period you like. It's in the menu options.

For quite a long time I try to access to the menu !
I found it fortuitously : A long press on UP button.
Anyway, thank you for this app !

Application is very usefull and well made, THANK YOU.

Recently i bought FR230 for my wife. Any plans to enable this app on FR230 ?
Looks like FR230 has everything thats mandatory to run this app.

I just installed the app on my Fenix 3HR.

The F3HR recognizes my HR from the onboard elevate sensor, but it seems like the app is searching for a cheststrap reading giving this status "Searching for HRM"
I installed following the guidance on the SportTracks blog - https://sporttracks.mobi/blog/tracking-hrv-garmin-watches.

I have read the instructions over and over - still not sure if it is supposed to giv HRV reading on the F3HR without using a cheststrap....

Am I supposed to get HRV data from the onboard sensor on the F3HR - or are you forced to use a cheststrap to get readings?

(I'm on the latest FW - v3.xx)

A bit of a moot point since the built-in sensor isn't accurate enough to provide an HRV calculation, see the link I referenced above.
