When it comes to heart rate variability (HRV), one common question is whether we should normalize HRV by heart rate.
Would it make more sense to divide HRV by resting heart rate interval?
I.e., HRV=50ms, RHR=50/min, heart rate interval = 1.2s
Normalised hrv = 50ms/1.2s
hello Julian, that is correct, so the normalization should be done in terms of "RR intervals" (e.g. HRV / avg RR), typically in milliseconds but your version is also fine, just scaled differently.
