Cluster Analysis of ECG Signals
 Dvořáček, Tomáš ; Chrobák, Martin (referee) ; Kozumplík, Jiří (advisor)
This bachelor thesis is engaged in problematics of automatic cluster analysis for ECG sinals. This bachelor thesis contains theory of pathology in cardiac rhythm and problematics of cluster analysis. Based on a gained knowledge, set of symptoms is made, which are used for cluster analysis using MATLAB interface and which results are evaluated.

Sampling Rate Conversion
 Chrobák, Martin ; Provazník, Ivo (referee) ; Kozumplík, Jiří (advisor)
This bachelor’s thesis is engaged in design of procedure for change of sampling rate of EKG signal using 3 methods: with positive integer factor D/I, with any factor (I=8) and with any factor (I=16). Sampling rate conversion should be realized from 500 to 360 Hz and from 360 to 500 Hz in time and frequency part of signal. For this, it is used a professional computing interface of MATLAB, which is perfect for processing of signals. The output from this work should be recommendation which filters (with how long impulse characteristics) are useful for this change of sampling rate.

Cluster Analysis
 Chrobák, Martin ; Ronzhina, Marina (referee) ; Kozumplík, Jiří (advisor)
This master’s thesis is engaged in usage of cluster analysis for ECG signal to separate normal QRS complexes from abnormal ones. For this, it is used two algorithms created in professional computing interface MATLAB. The outputs from this master’s thesis are dendrograms, which divide QRS complexes into abnormal and normal clusters, and Pearson correlation coefficients.
