A method of measuring, with electronic instruments, the heart beat of a fetus in response to the contractions of the mother's uterus.
recording of the baby's heartbeat and the uterine contractions during labor.
A method of tracking contractions and fetal heart beats (tones) with an external ultrasound belt or an internal electrode attached to the baby's scalp along with an internal catheter measuring the strength of contractions.
Electronic machine which detects heart motion and uterine contractions then records them on graph paper. Attached externally with elastic straps to the maternal abdomen.
The continuous monitoring of the baby during labour, either through transducers which are attached by belts to the mother’s abdomen, or by a scalp electrode which is inserted through the mother’s vagina and attached to the baby’s scalp.
The use of external and internal devices that record the fetal heart rate. An externally applied ultrasound transducer converts sound energy into electrical energy which is recorded on a graph. After rupture of the membranes, an electrode can be applied via the maternal vagina to the fetal scalp to obtain a fetal ECG. The maternal uterine contractions also are recorded on the graph so that they can be related to the fetal heart rate, to indicate fetal distress.
A method in which electronic instruments -- placed internally or externally -- are used to record the fetus's heartbeat and contractions of the uterus.
