1. A method of obtaining information that corresponds to an R-R interval of electrocardiogram from a pulse-wave of a human body, said method comprising the steps of:

  • detecting said pulse-wave of the human body in a predetermined period;

    differentiating said detected pulse-wave to provide a speed-pulse-wave;

    taking points of said speed-pulse-wave into peak values on the basis of a first threshold value;

    measuring intervals of said peak values; and

    substituting said intervals for the R-R interval of said electrocardiogram.
