Heart Rate Variability Premium Metric--- help interpreting

‎12-22-2020 14:51

‎12-22-2020 14:51

I gave my 14 year old daughter my FitBit because she has some chronic conditions that really affect her sleep. I was very interested to see the new Heart Rate Variability metric, and the app and research I see says that higher is better than lower. I am having a hard time finding normative ranges, especially for her age... (I have even been looking at scientific papers!) I read that 0-50 was not good, 50-100 was ok, room for improvement- not sure above that? Does anyone have a good resource for this? Thanks!

Hi @DogwoodNC, and welcome.

I think your question is going to be very, very difficult to answer. For one, almost all the HRV data I've seen is for age range 18 and up. Second, that there are chronic conditions involved make the question more complex. A doctor would likely be the best resource on taking the data and conditions into account.

I did fine one study Umetani et. al, 1998 for normal ranges for ages 10-99, that you might want to show her doctor and see what they think.  Hope this helps.
