LFA may inform noninvasive fetal monitoring; hypothesis-generating in this cohort and requires prospective validation before practice change.
Does power spectral analysis of fetal heart rate fluctuations correlate with gestational age and fetal blood gas levels in normal and IUGR fetuses?
Measurement of low-frequency areas in fetal heart rate fluctuations correlates with gestational age and fetal blood gas levels, potentially serving as a quantitative index of fetal well-being.
Ohta et al. (1999) studied this question.
