Resting cardiac rate and variability were obtained on a group of subjects seen first in the last trimester of prenatal life and over the first year of postnatal life. Maternal cardiac rate and variability were also obtained. The data indicate no relationship between maternal and fetal or infant data. Moreover, there are clear developmental patterns of resting cardiac response over the first year of life with rate and variability showing linear decreases.
