Discrimination of normal and at-risk populations from fetal heart rate variability

Using clinically measured intrapartum cardiotocography (CTG) data, the objective of this study was to compare the discrimination of fetal heart rate variability in the low frequency (LF, 30-150 mHz) movement frequency (MF, 150-500 mHz) and high frequency (HF, 500-1000 mHz) bands for two at-risk groups: fetuses experiencing either neonatal depression or metabolic acidosis. These parameters had statistically significant differences when comparing normal fetus and these indexed groups.
