Day to Day Variation in Fetal Heart Rate Variability

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.

Inclusion Criteria:

• Healthy singleton pregnant women with an expected healthy fetus

Exclusion Criteria:

• fetal malformations, multiple pregnancy, obstetric complications, maternal chronic disease and labor. Low birth weight or malformation diagnosed at birth.
