Srovnání abdominální fetální elektrokardiografie a dopplerovského ultrazvuku pro potřeby monitorace plodové srdeční frekvence

Abstract

The purpose of my thesis is the comparison of two non-invasive methods of fetal monitoring - a fetal electrography (fEKG) and a cardiotocography (KTG). The theoretical part of the thesis introduces my research of the topic theory and describes the current state and individual methods of fetal monitoring used in clinical practice. The first part of the experimental section of the thesis inquires into the problematics of the cardiotocographic record digitalization. The second part deals with the comparison of KTG and fEKG in terms of fetal heart rate based on the measurement of data from five tested subjects. The nonadaptive JADE method, based on the analysis of independent components, was used to extract the fetal ECG from the abdominal recording. The MATLAB software development environment was used for the data processing. The conclusion of the work focuses on the evaluation of the results using Bland-Altman graphs.
