ABSTRACT:
An apparatus for determining a characteristic point of a pulse wave detected from a living subject, the apparatus including a pulse-wave detecting device which detects a first pulse wave from a prescribed portion of the subject, a pulse-wave modifying device for modifying a waveform of the first pulse wave detected by the pulse-wave detecting device, according to a predetermined relationship between first pulse wave, and second pulse wave whose characteristic point is clear, and a characteristic-point determining device for determining a characteristic point of the modified waveform of the first pulse wave.
