You can analyze your heart rate variavirity to detect autonomic nerve state, with calculating parameters below.

Parameter Description
AVNN Average of all RR intervals
SDNN Standard deviation of all RR intervals
rMSSD Square root of the mean of the squares of differences between adjacent RR intervals
pNN50 Percentage of differences between adjacent RR intervals that are greater than 50 ms
LF Total spectral power of all RR intervals between 0.04 and 0.15 Hz
HF Total spectral power of all RR intervals between 0.15 and 0.4 Hz
LF/HF Ratio of low to high frequency power

Power spectrum of HRV is calculated with Auto Regressive (AR) method.
