ABSTRACT:
A cardiovascular system observation method using a computer processor on the basis of pulse wave amplitude data obtained from a patient in a compressed state which changes, said method comprising: process steps for forming measurement patterns expressing the transition of pulse wave amplitude values by smoothing minute fluctuations of said pulse wave amplitude data and normalizing the pulse wave amplitude values and pulse wave intervals of said pulse wave amplitude data; process steps for extracting the features of the measurement patterns; and process steps for judging the pattern shape to judge reference pattern groups to which said measurement pattern belongs by using said features.
