Multifractal analysis of fetal heart rate variability in fetuses with and without severe acidosis during labor.

摘要

We performed multifractal analysis of fetal heart rate (FHR) variability in fetuses with and without acidosis during labor. Multifractal analysis was performed on fetal electrocardiograms in 10-minute sliding windows within the last 2 hours before delivery in 45 term fetuses divided in three groups according to umbilical arterial pH and FHR pattern: group A had pH >/=7.30 and normal FHR, group B had pH >/=7.30 and intermediate or abnormal FHR, and group C had acidosis (pH
