Abstract

The spatial position of a fetus within the womb is determined and monitored through analysis of ECG waveform data received from a set of electrodes that are attached to a maternal abdomen in a predetermined configuration. The waveform is compared with a set of predefined stored templates to determine the position of the fetus. An event logger may determine the number of fetal movements during a period of time.
