Does acute hypoxia alter the power spectral pattern of heart rate variability in fetal lambs?
Power spectral analysis of heart rate variability detects autonomic changes during acute hypoxia in fetal lambs, indicating potential utility for quantitative fetal monitoring.
Min et al. (2002) studied this question.
