Claim 7:
8. The computer readable medium according to claim 4,
wherein, in the procedure for finding the index regarding the vibration ascribable to the blood flow rate change, the computer is caused to execute:
a procedure for specifying one set or more of two of the waveform components in the range of the biological signal time-series waveform corresponding to the ventricular filling period to the isovolumetric systole, in the biological signal, and generating a scatter plot by using total amplitudes of the two waveform components; and
a procedure for finding a slope of a regression line of a plot group plotted in the scatter plot, the slope of the regression line of the plot group being the index regarding the vibration ascribable to the blood flow rate change.
