[Prolonged fetal monitoring, ultrasonic telemetric registering. Methodology. Applications].
Studying the fetal heart rate is the method of choice for monitoring fetal wellbeing. All the same, when repeated records are made, but only over a short time, no permanent control is carried out and this means that some very high risk fetuses are not monitored properly. but all these involved using electrocardiograms to record the fetal heart rate and this was not a practical proposition because of the number of artifacts that were produced. the authors suggest using a new method of observing the fetal heart rate over a long period of time based on telemetric transmission of the rate using an ultrasound machine. They show the results and also the difficulties of using this apparatus as well as the prospects for studying fetal physiology in this way.
