  • Publication number: 20050090720
    Abstract: A pulse analyzing apparatus includes a measuring unit, a capture unit for processing a pulse signal from the measuring unit, and an operation analyzing unit for calculating the pulse signal processed by the capture unit. Thus, the pulse analyzing apparatus uses a multi-way measurement process to simultaneously measure the pulse signals of different portions of a tested person, thereby simplifying the measurement process and saving the time.
