PATIENT SIMULATOR – MATERNAL & FETAL SIGNAL GENERATOR OF NON-INVASIVE ABDOMINALLY RECORDED ECG & EHG BIOPOTENTIALS

Abstract

This paper describes the design and develop­ment process of a multi-channel electrophysio­logical sig­nals generator based on LabVIEW program­ming environ­ment and its associated data acquisition measurement cards (DAQmx). Special attention is paid to the reconstruction of realistic non-invasive signals in terms of maternal and fetal cardiac and uterine electrical activity. Main concern was to build a functional prototype that is able to generate and module synthetical signal in real-time without any losses of the signal’s quality, which ultimately can produce a contribution to the development of new diagnostic methods.
