MEDICAL AND BIOLOGICAL MEASUREMENTS

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