A method used to measure the unborn baby's heartbeat, the mother's heartbeat, and contractions of the mother's uterus. To measure the baby's heartbeat, an ultrasound transducer is placed on the mother's abdomen, close to the baby's heart. To monitor contractions of the mother's uterus, a pressure sensor is placed on the mother's abodomen. Amplitude, frequency and duration are monitored with an interuterine catheter. Monitoring of the baby's heartbeat can also be accomplished internally by placing an electrode through the cervix onto the baby's scalp. Also known as an electronic fetal monitor.
