HRV View: shows HRV information
E.1. Time Domain HRV
E.1.1. AVNN: mean of all the intervals in ms
E.1.2. SDNN: standard deviation all RRIs over the complete test duration in ms
E.1.3. SDANN: standard deviation of the 5 min means in ms
E.1.4. ASDNN: mean of the 5 min standard deviation in ms
E.1.5. NN50: the number of RRI difference of successive RRIs greater than 50ms
E.1.6. PNN50: NN50 as a percentage of all allowed RRIs
E.1.7. RMSSD: root mean square of successive differences in ms
E.1.8. TINN: triangular index interval is the baseline width of the distribution measured as
a base of a triangle approximating the RRI distribution
E.2. Frequency Domain HRV
E.2.1. VLF: very low frequency power (0.00333 Hz to 0.040 Hz)
E.2.2. LF: low frequency power (0.040 Hz to 0.150 Hz)
E.2.3. HF: high frequency power (0.150 Hz to 0.400 Hz)
** During measure the HRV, minimize move.
