Thank you so much for your reply!
Personally I am still stuck with extremely elevated hrv values and lower than normal HR. But to hear that your values were not tied to afib with svr is somewhat reassuring. Again, thank you!
Just to add an anecdotal note for others reading this: I do not trust Garmin HRV data at all. My Epix Pro says that my HRV baseline is around 25 ms, which is really rather low. It does wander up and down in a manner consistent with training stress etc., but I think that the most likely explanation for the low value is that it’s nonsense. I have measured my HRV with a strap and Elite HRV app a load of times and it’s always more like 55-60 ms. So if anyone is seeing low HRV values from a watch worn overnight, I wouldn’t panic - if that’s your only reason for concern then the simplest explanation (duff data) is quite likely to be the correct one.

Ive only had a Garmin watch capable of HRV since January. It seems well behind the things for me. Recently it climbed back into ‘balanced’ for a week and was still balanced the night after I was hit by something which dehydrated big time through spending all night in the bathroom and only sleeping 1.5hours (I’ll spare you the full details). Only after three days, as I started to recover did it fall to ‘low’, and even yesterday when I felt fully recovered and smashed a training session it was still ‘low’. Only today it has moved to an orange ‘unbalanced’ state. Like you I don’t trust it either.
Depends on how you interpret the data. Multiple race days in a row can lead to low HRV, as can taking a complete week off. You can induce high hrv with lots of zone 1/2 training / reintroducing consistent aerobic training or taking a couple of rest days following intense training. Yes, HRV and RHR can be useful, but looking at your own trends in training, sleep, motivation, etc must still be used.
