Abstract:
In this study, 41 asymptomatic subjects (22 men and 19 women, 20 to 60 years of age) were enrolled. The PWV was measured both by dual-channel PPG (PWV-DVP) and by the proposed PWV instrument, Pulse Wave Velocity by Digital Volume Pulse Easy (PWV-DVPE). The developed system recorded digital volume pulse simultaneously from both the finger and ear. Time of pulse transition was measured on the time delay difference between two digital volume pulses. The PWV was calculated by dividing the distance between finger and ear by that of transit time. PWV-DVPE's capability of precise self-monitoring arterial stiffness is being proven in this study. In home care area, only few minutes is needed for self arterial stiffness assessment. Therefore, early self-monitoring of cardio-vascular dys-function and arterial stiffness is easily and effectively achieved.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
