METHOD FOR EVALUTING VASCULAR AGING USING FREQUENCY DOMAIN ANALYSIS OF PULSE WAVES

摘要

PURPOSE: a kind of evaluation blood vessel aging is arranged to eliminate pulse wave inflection point using the frequency-domain analysis appears in pulse waveform photoplethysmogram according to the time, by analyzing in frequency domain. ;CONSTITUTION: detection pulse, according to time (S71). Pulse wave becomes digital signal (S75). Impulse wave is converted into digital signal and is converted to frequency domain (S77). Pulse wave is converted into frequency domain criteria (S79). The peak value epoch of each power's data standardize pulse wave (S81) according to the peak value of detection. Regression analysis about power is performed. Electric power is the curve graph for analyzing the function of age (S83). ;The 2012 of copyright KIPO submissions
