Bioimpedance signal processing
 Soukup, Ladislav ; Kolářová, Jana (referee) ; Provazník, Ivo (advisor)
The aim of this thesis is a study of impedance cardiography and its subsequent use in determining the cardiac output. The calculation in this work uses three default types of biological signals: the ECG signal to gallop and the impedance cardiography. There are identified the necessary parameters of the signals, especially heart rate, heart sounds (S1,S2) and the derivative impedance cardiography. This method of determining cardiac output is non-invasive and is easy to perform for doctor and patient, which is very important for risky patient especialy. Disadvantage is imprecision, that is eliminated by modifying the algorithm of the calculation. User interface for processing all the necessary signals and the subsequent calculation of cardiac output was implemented in MATLAB programming environment and is optimized for data measured and processed in the ISI ASCR.
