The Spectral Analysis of a Signal of Pulse Waves for Diagnostics of a Condition of Physiological Systems of an Organism


Yu.P. Mukha, T.S. Hvorost, O.A. Avdeuk

Various approaches to research of characteristics пульсовой waves are considered, and also examples of usage of the given methods for handling and the analysis of biosignals are resulted. High-frequency oscillations in a signal пульсовой waves are researched. On the basis of correlation coefficient presence between a rhythm of heart and harmonics of a spectrum Fourier in a range 1 - 50 Hz, the actual research problem of the given parameter from the point of view of possible physiological states, for example intensity levels регуляторных systems is revealed. Changes of the frequency characteristics, amplitudes of harmonics and discretization of a spectrum Fourier reflect changes of the functional state of an organism. From 10-3 to 20 Hz the blood-groove can contain in a range of frequencies some the various periodic components expressed totally in the form of a signal FPG, and having various frequencies, amplitude and the form. Analyzing parameters пульсовой waves, it is possible to receive the valuable information on a state of cardiovascular system, first of all-peripheral blood supply of a researched organ.
