It's a component of the poincare analysis.
Consider this snippet of code:
import heartpy as hp
data, _ = hp.load_exampledata(2)
wd, m = hp.process(data, sample_rate = 100.0, high_precision = True)
hp.plot_poincare(wd, m)
This gives the following plot:
This plots the peak-peak intervals with RR(n) on the x-axis and RR(n+1) on the Y axis.
SD1 is the standard deviation of intervals along the identity line (x=y) SD2 is the standard deviation of intervals perpendicular to the identity line S is the surface area of the ellipsoid described by SD1 and SD2
Hope this answers your question :)
Cheers

Hi,
thank you so much for this great pack! I'm just wondering which is the meaning of "s" that is listed among the other indices. It get printed by this block below:
