WAVELET-BICOHERENCE OR NORMALIZED WAVELET-BISPECTRUM BASED ANALYZING OF FETAL HEART RHYTHM

Abstract

processes diagnostics on the analysis of electrocardiograms (ECG). Different be groups: stationary and non-stationary. Stationary signals have statistical and spectral characteristics that are constant over time, for a comprehensive description of which the Fourier transform is sufficient. ECG rhythmogram be attributed to the class of chaotic processes. The of a chaotic process change time, and other be used to analyze their method is wavelet the of work, a method for assessing the fetal heart rhythm, based on extracting an informative feature from the wavelet bicoherence of the rhythmogram.
