A new approach to pulse signal rhythmic structure analysis

Desova A. A., Guchuk V. V., Dorofeyuk A. A.

A new approach to investigate a radial artery pulse signal rhythmic structure is considered based on a simultaneous analysis of a set of oscillatory components determined by parameters of various elements of unit oscillations. Based on a comparative analysis of the spectral density types defined by different parameters of a pulse signal, an essential distinction between them has been revealed. An opportunity of increasing the number of informative features by means of simultaneous analysis of pulse signal rhythmic structure oscillatory component set is shown. The study has been carried out using experimental material obtained during children’s clinical examinations focused on detecting the initial stage arterial hypertension in infancy and adolescence. The informativeness of the pulse signal rhythmic structure parameters was estimated as applied to this task, showing that maximum informativeness is inherent to indicators defined by oscillatory components of the pulse signal dicrotic wave temporal parameter.
