Využití komplexních adaptivních metod zpracování signálů pro zpřesnění diagnostické kvality abdominálního fetálního elektrokardiogramu.

Abstract

This dissertation deals with the application of complex adaptive methods of signal processing for refining the diagnostic quality of abdominal fetal electrocardiogram. The FECG (fetal electrocardiogram) contains this sort of information that is valuable for doctors in monitoring and diagnosing of endangered fetuses in the course of pregnancy or in the childbirth. The doctoral thesis concentrates primarily on external abdominal non-invasive fetus monitoring technique, which, contrary to the classical internal invasive monitoring, entails a number of problems with record quality. In real conditions, the diagnosed fetal electrocardiogram is downgraded by amount of unwanted components. In particular it is caused by superposition of these factors: stronger maternal electrocardiogram MECG, technical artefacts (transmission grid interference) and biological artefacts (uterine contraction, motion artefacts). This dissertation is aimed at such adaptive methods of FECG signal processing, whose ambition is to clear any doubts in the evaluation of more discreet method of external FECG monitoring.
