What is fetal heart rate monitoring?
It records, on paper or on a screen, the beats of the baby's heart. It is also called cardiotocography (CTG), fetal monitoring, or a non-stress test (NST) when no contractions are present.
Two sensors are placed on the abdomen: an ultrasound sensor picks up the baby's heart rate, and a pressure sensor records the uterine contractions. It does not hurt and uses no radiation.
