Heart rate variabirity (HRV) analysis tool with Polar H7/H6 on MacOSX.
You can analyze your heart rate variavirity to detect autonomic nerve state, with calculating parameters below.
|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.
