Zpracování plodového elektrokardiogramu pomocí metod šablonového odčítání

Abstract

The aim of the diploma thesis is to process fetal electrocardiogram using template subtraction. At the beginning of the thesis, the issue of the development of the fetal cardiovascular systém is discussed and then thesis is devoted to a review for template subtraction methods and their mathematical description. The practical part is focused on signal processing using template methods with subsequent detection of individual fetal QRS complexes. Evaluation of fetal ECG extraction is based on fetal heart rate. Method used in thesis are TS, TS – Cerutti, TS – Suzanna, TS – PCA and TS – LP. The extracted fECG signals are plotted in graphical user interface in Matlab environment.
