Heart rate variability is the tiny difference between successive heart rate
interphase. It comes into being from the modulation of autonomic tones on the
sinus nodal autonomy. And it makes several milliseconds difference and
fluctuation between heart rate interphase. HRV analysis is a sensitive and
non-invasive method to estimate the function of autonomic tones.

22.7.1 R-R Interphase Value Histogram
It reflects the distribution of R-R interphase value. The abscissa is the
R-R interphase, and the ordinate is the numbers of R-R interphase. Histogram
can reflect the range and extent of R-R interphase variety.
Select【R-R Histogram】of the【HRV Analyze】menu , then the R-R
interphase value histogram can be displayed as follows:
