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