Day to Day Variation in Fetal Heart Rate Variability ((FHRV))

November 1, 2022 updated by: University of Aarhus

Day to Day Variation in Fetal Heart Rate Variability Based on Fetal Electrocardiography (FECG), in a Standardized Setting: A Cohort Study

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.
