[High-frequency oscillations in a pulse wave signal and their relation to differential blood count leucocytes].
High-frequency oscillations in a pulse wave signal in the range of 1-50 Hz and their relation to differential blood count leucocytes have been investigated. It is shown that the correlation coefficients grow in the frequency range of 1-12.5 Hz between high-frequency oscillations in a pulse wave signal and stab neutrophils, monocytes and segmented granulocytes. The procedure of smoothing the coefficients of harmonic variation has been proposed.
