Hi Lyle, there are errors in the analysis, you have much parameters out of scale.
You have to use the filter option.
Then, there is an error in the choice of the time analysis, this give you incorrect data and FFT spectrum!
HRV has specific rules, if you don’t respect their, you’ll have only “numbers”.
You can send me your file: armandovinci@gmail.com and I’ll do an analysis for you.
