Gaps in HRV data during night

Jasper
9 months ago

During the last night's this is what my HRV readings look like.

The data is getting inconsistent because of this. Is anyone familiar with this problem and might know of a solution?

    Garmin will not investigate further as they already concluded that it is due to sleeping patterns and other stuff.

    If HRV si a must have for you, I would recommend accepting the refund. Unfortunately Garmin won’t admit this is a software issue.

    All,

    Thank you for sharing your concerns regarding HRV gaps. We are still investigating reports, but have still determined that the gaps are due to restricted blood flow. In case you missed my comment from 4 months ago, here was my update which is still true: 

    After further investigating these reports, we've determined that the gaps are due to restricted blood flow. Please see the following from What is Heart Rate Variability (HRV)?: 

    In some cases gaps in HRV data may happen overnight while the heart rate data shows for the full night. This is due to HRV having a quality requirement. If that requirement is not met, HRV will not be recorded during that time. These gaps in information can form when the heart rate sensor has difficulty getting heart rate. It can be caused by sleeping on your wrist, having the band too loose, or anything that causes a block of blood flow or movement of the watch on the wrist. We recommend wearing the watch with a snug fit that does not cut off circulation. A lot of movement while sleeping can cause this to happen as well so if you are an active sleeper you may see these gaps in your HRV information. 

    If you have any further questions or concern regarding this, please reach out to Garmin Product Support directly.
