Abstract—A new method has been proposed for processing the nonstationary rhythmogram signal recorded in the head-down tilt test (HDT). The method is based on the continuous wavelet transform of the heart rate signal with a frequency modulation component. The rhythmogram signal was shown to be a system of heart rhythm bursts of different frequency ranges. Quantitative indices were developed to analyze the system of bursts. The translational signal transfer method was used to eliminate the boundary effects that arise in analyses of the low-frequency components of the rhythmogram signal.
