Abstract:
1. Apparatus for determining fetal spatial presentation and/or position within a uterus comprising: a set of electrodes adapted to be attached to a maternal abdomen in a predetermined configuration; an input for receiving ECG waveform data from the set of electrodes; a plurality of prestored sets of fetal ECG complex templates, each template corresponding to a specific fetal spatial presentation and/or position, each prestored set of templates ascribed to a respective predetermined electrode configuration; a waveform pre-processor for identifying a number of fetal ECG complex waveforms within the data; a memory for storing the plurality of fetal ECG complex templates; and a comparator for determining fetal spatial presentation and/or position within the uterus, the comparator comparing the shape of each received waveform with the plurality of fetal ECG complex templates ascribed to the predetermined electrode configuration and determining which template best matches the identified fetal ECG waveform.
