Does intrapartum acidosis affect specific components of fetal heart rate variability during the last hour of labour?
Marked fetal acidosis is associated with specific changes in fetal heart rate variability, reflecting autonomic nervous system compensation during the last hour of labor.
Siira et al. (2005) studied this question.
