title: Fetal heart rate accelerations and fetal movements in twin pregnancies.
abstract: The rate of fetal heart rate accelerations associated with fetal movements to total fetal movements of twin pregnancies was found to be significantly lower than that of pregnancies with singleton infants. The number of fetal heart rate accelerations was similar. As fetal heart rate accelerations are reflective of fetal movements, the results indicate increased fetal activity in twins that is related to an additive effect of two normally active fetuses.
