Abstract
This article is devoted to analysis of the noise immunity of pulse wave’s contour analysis. Different approaches to the implementation of the pulse wave’s contour analysis were considered. It was demonstrated, that classical approach for the morphological analysis of the pulse wave based on using stiffness index and reflection index do not provide sufficient diagnostic accuracy due to the instability of the maximum detection of the reflected wave. The technique of contour analysis based on spectral transformation of replicated fragments of the pulse wave was proposed. As a diagnostic index the ratio of the amplitudes of the first two harmonics of the spectrum was used. The influence of uncertainty measurement of the pulse wave amplitude on determining the accuracy of the morphological analysis of the pulse wave realized by different methods was researched.
