| Popis: | Visual and computerized analysis of pulsograms revealed the entire daily (24-h) wave structure of the cardiac rhythm in healthy children. Only two waves characteristic of the cardiac rhythm of a healthy child follow each other all 24 h of the day. These are the respiratory and blood pressure waves. Slower waves (from several minutes to several hours in length) are encountered in the cardiac rhythm in the form of interesting regular alternations. Comparison of the periodic structures obtained on the basis of spectral analysis and from the pulsograms illustrates the limited possibilities of the Fourier spectrum in the analysis of nonstationary stochastic processes as compared to the visual analysis of pulsograms. |
