ABSTRACT:
An apparatus for measuring a propagation velocity of a pulse wave which is propagated through an artery of a living subject, includes an electrocardiographic-waveform detecting device which detects an electrocardiographic waveform from the subject, a pulse-wave sensor which is adapted to be worn on the subject and which detects the pulse wave from the subject, a time-difference determining device for determining a time difference between a first periodic point relating to the detected electrocardiographic waveform and a second periodic point relating to the detected pulse wave, and a propagation-velocity determining device for determining the propagation velocity of the pulse wave based on the determined time difference.
