Wavelet analysis of nonstationary heart rate variability in a head-up tilt-table test
Tóm tắt
Heart rate variability during the head-up tilt test (HUT) was investigated using an automated setup of dynamic positioning in the gravity field. The wavelet theory was applied to find the dynamics of changes in the spectral properties of rhythmograms during the transitional steps of HUT. Quantitative parameters (spectral integrals, instantaneous maximal frequencies, nonstationarity factors) that describe the transients of such nonstationary HUT were calculated.
