Brief Summary

There is growing evidence in the field of fetal heart rate variability revealing the fetal neurological state. Furthermore, fetal heart rate variability has shown potential as fetal surveillance in fetal growth restriction. This study aim to investigate the association between fetal heart rate variability and doppler flow changes in growth restricted fetuses.
