Abstract

OBJECTIVE:

In this study, we wanted to model the emergence of coupling between fetal cardiac and somatic activity in normal and at-risk fetuses.

STUDY DESIGN:

One hundred six fetuses of uncomplicated pregnancies were longitudinally monitored at 20, 24, 28, 32, 36, and 38 weeks of gestation by using a fetal actocardiograph and computerized data collection. Twenty-six fetuses of complicated pregnancies were also included. Statistical time series analysis techniques were used to examine the relation between fetal movement and fetal heart rate.

RESULTS:

A linear increase was found in the magnitude of the cross-correlation function between fetal movement and fetal heart rate as gestation advanced, with coalescence around a peak lag of 5 seconds by 32 weeks. Fetuses that delivered before term evidenced accelerated fetal movement and fetal heart rate coupling, whereas fetuses affected by deleterious conditions showed a decline in developmental trajectory.

CONCLUSIONS:

The cross-correlation between fetal cardiac and somatic activity is an indicator of neuroregulation in human fetuses.
