Day to Day Variation in Fetal Heart Rate Variability

University of Aarhus44 enrolled

Overview

This study evaluates the day-to-day variation in fetal heart rate variability based on non-invasive fetal-ECG (NI-FECG). Furthermore, the effect of fetal movements on fetal heart rate variability will be assessed.
