Detection of pathologies in ECG signals
Němec, Radek ; Mézl, Martin (referee) ; Kašpar, Jakub (advisor)
This thesis attempts with methods for detection of pathologies in ECG signals. The first part is focused on the basic theory of heart anatomy, electrocardiography and individual heart pathologies. The second part describes the preprocessing of ECG signals, detection of QRS complexes and detection of individual pathologies. In the third part the detector is being tested on CSE database and my own measured data.

Mechanisms of conduction system development in vertebrates
Šaňková, Barbora ; Sedmera, David (advisor) ; Neckář, Jan (referee) ; Melenovský, Vojtěch (referee)
Group of specialized cells that form cardiac conduction system is responsible for generation and coordinated propagation of the electrical impulse in the heart. Changes in its development can be connected with arrhythmias; therefore, a good level of knowledge is necessary and relevant for basic science and clinical practice. For correct development of the conduction system are important genes coding gap junctions proteins, ion channels, transcription factors and other molecules involved in signaling cascades (endothelin, neuregulin). Development of conduction system is determined in addition to genetic factors also by epigenetics and environmental factors. This thesis with its individual papers on which it is based is addressing different aspects of conduction system development, which appears to be a complex process. Another feature which is linking all papers together, is the methodological approach enabling us to study function of the conduction system - optical mapping. In the first publication we studied by the means of in vitro organ culture the impact of work load without interfering hemodynamics on the conduction system maturation in the chick embryonic heart. The phenotype observed during experiments was developmental regression of conduction system maturation together with changes in...
