Quantification of the fetal heart rate variability by spectral analysis in growth-retarded fetuses.
The analysis of short-term variability of fetal heart rate in the frequency domain was performed. The fetal activity states (quiescence, trunk rotation, body movements, fetal breathing movements) were taken into account. The differences between the shapes of power spectra in physiological and growth-retarded fetuses were discussed.
