Intraventricular conduction time in fetuses born with growth retardation

Averaged QRS complexes were studied in 26 pregnancies characterized by fetal growth retardation. A high correlation was found between QRS duration and infant birthweight and the QRS interval closely reflected the abnormal cardiovascular conditions that occur in the malnourished fetuses. QRS determination provides a complementary and accurate method to detect and assess an inappropriately growing fetus.
