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.
| 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.
