Relationship between Vascular Elasticity and Human Pulse Waveform Based on FFT Analysis of Pulse Waveform with Different Age

Abstract

This study proposed a method using the value of amplitude of FFT frequency to evaluate the vascular elasticity (VE). Although personally different features of subject and accidentalia in the measurements were existing, the result of the experiment reflected the relationship between VE and the pulse waveform comparatively well, and the relationship between the VE and age indirectly. The value of amplitude of FFT frequency could reflect the subtle variation of the pulse waveform better compared with the K value evaluating the VE reported in the published literature. This method showed potential in the respect of non-invasive VE detecting and put forward a new and doable suggestion for the study of VE.
