Abstract
A method of obtaining information that corresponds to the R—R interval of electrocardiogram from the pulse-wave of a human body. The method is comprised of steps of detecting the pulse-wave of a human body in a predetermined period, differentiating the detected pulse-wave to provide a speed-pulse-wave, measuring intervals of peaks of the speed-pulse-wave, and substituting the intervals of peaks of the speed-pulse-wave for the R—R interval of the electrocardiogram.
