Automatic Segmentation of Cardiac Tissue Movement from Ultrasound Record
Munzar, Milan ; Orság, Filip (referee) ; Mráček, Štěpán (advisor)
This thesis describes design and implementation of method, which determines beginning of heart beats in echocardiographic record. Design of this method is built around pyramidal Lucas-Kanade algorithm and fast Fourier transform. This method is implemented in C++ language with OpenCV and FFTW libraries. Analysis of the implementation has shown, that this method is sensitive to anomalies in echocardiographic record. This method is developed as a part of the project for an analysis of echocardiographic records for st. Anna hospital at Brno.

Detection of atrial fibrillation in ECG
Húsková, Michaela ; Vítek, Martin (referee) ; Maršánová, Lucie (advisor)
Aim of this thesis is description of problems of atrial fibrillation and methods that could be used for detection in the electrocardiogram. The introductory part of the theoretical analysis deals with the principle of electrophysiology of the heart and mainly the pathophysiology of atrial fibrillation. Additionally the work is focused on describing methods on automatic atrial fibrillation detection and capabilities of PhysioNet database. In the practical part methods are implemented in the MATLAB environment. After using the statistics to evaluate the quality of the parameters, the automatic classification of the data was performed by the method of The Nearest Neighbour. Finally, the accuracy of testing is presented.

Knowledge of nurses in twelve lead ECG recording
Duda, Jiří ; Matulová, Jana (advisor) ; Menšíková, Monika (referee)
Author: Jiří Duda Institution: Charles University Faculty of Medicine in Hradec Králové Department of non-medical studies Title: Knowledge of nurses in twelve lead ECG recording Supervisor: Mgr. Jana Matulová Number of pages: 94 Number of attachments: 3 Year of defense: 2022 Keywords: ECG, cardiac physiology, nurses, knowledge of nurses, cardiology The bachelor thesis deals with the problems of correct ECG recording by nurses in the environment of a cardiology clinic. The theoretical part of the thesis deals with anatomical description of the heart, comprehensible description of creating excitation signal in the heart and its travel through cardiac conduction system. Furthermore, this part deals with all types of ECG recordings, correct ECG monitoring technique, description and differences between ECG leads, physiological ECG curve and its basic description and pathological ECG curve with the most frequent heart rhythm disorders. The empirical part examines knowledge of nurses in the correct ECG recording using non-standardized questionnaire survey.
