QRS Complex Detector
Kubík, Adam ; Provazník, Ivo (referee) ; Smital, Lukáš (advisor)
The aim of my thesis is to introduce issue of detection of QRS complex by squaring and envelope detection. The first part focuses on creation and scanning of heart electrical activity. Afterwards, the most frequent types of disturbance of EKG signal and their filtering are described. The second part is about real application of signal filtration and emphasis of QRS complexes using the methods which are mentioned above. Practical part is externalized in Matlab program. And signals from CSE library are used to test efficiency of the detectors.

QRS Complex Detector
Balík, Zdeněk ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
The subject of the bachelor's thesis called QRS complex detektor is introduction with the basic princips of detection based on exponentiation and envelope of filtred signal. In the first part of this thesis is subscribed the emergence of electrical activity of the heart and the ways of its scanning. Further are in the thesis described characteristics and typical disruptions EKG signal and their filtration. The remaining part is devoted to specific methods of detection of the QRS complex. Practical realization is carried out in the programming environment MATLAB.
