Abstract :
Two sets of photoplethysmographs were used to record arterial pulse waves. A linear predicting function that could predict pulse wave velocity (PWV) by means of age and blood pressure was obtained, and the values computed by this function were subtracted from the measured PWVs. These residuals of the normal subjects were compared with those of the patients in each disease category. The difference between the residuals of normal subjects and those of the patients was not significant
