Hi,
As there seem to be several ways of measuring and also presenting HRV (SDNN, SDRR, rMSSD, ln(rMSSD), ln(RMSSD)x20, PNN50 etc...,) I'm curious what unit of measurement Garmin uses for the HRV-status value (i.e the average nightly value). When doing a Health Snapshot, two results are presented: RMSSD and SDRR. But what is the unit for the nightly average value?
Thanks!
