title: [High-frequency oscillations in a pulse wave signal and their relation to adaptation responses].
abstract: High-frequency oscillations in a pulse wave signal in the range of 1-50 Hz and their relation to heart rhythms have been investigated. Informative parameters to estimate the adaptation reactions have been determined using the Kohonen maps, the results of simulating the pulse wave signal (single rheocycles), and the experimental data. The coefficient of harmonic variation was used as an informative parameter. It was shown that the space of signs in the frequency range of 1-12.5 Hz, formed on the basis of the coefficient of harmonic variation, possesses a significant degree of structuring relative to the distribution of data for different types of adaptation reactions.
