Influence of System Configuration on the Quality of Non-Invasive Fetal Electrocardiography Measurement

This paper introduces a pilot study investigating the influence of various parameters on the quality of electronic fetal monitoring based on non-invasive fetal electrocardiography. The investigation was carried out as a necessary step in development of an embedded system for fetal monitoring designed as a wearable device. The experiments included measurements of four different configurations on a subject at 34th week of pregnancy by means of 2.0 generation g.USBamp biosignal amplifier from g.tec medical engineering company. The study results in the recommendation of the most suitable system configuration and the electrode placement in terms of the signal quality and the clinical feasibility.
