ECG Biofeedback
Macková, Pavlína ; Kolářová, Jana (referee) ; Sekora, Jiří (advisor)
The master’s thesis is focused on the possibilities of measuring heart rate of ECG signal and its use in therapeutic game of ECG biofeedback. This thesis describes the way of measuring ECG with acquisition unit Biopac and analyzes signal processing for measurement of heart rate – algorithms of QRS detection, HRV analysis. Realisation of therapeutic is designed for applications in Matlab.

Measurement and analysis of ECG signal
Černohous, Lukáš ; Vítek, Martin (referee) ; Harabiš, Vratislav (advisor)
In the first part, this thesis focuses on theoretical knowledge about ECG signal generation, its measuring and filtration. Furthermore it examines the R-wave as the most significant portion of the QRS Complex, describes the LabVIEW environment and the Vernier LabPro interface. The second part of the thesis then shows one of the possible ways of the R-wave detection and the subsequent heart rate measurement, which is then implemented by a program designed in LabVIEW environment. In the conclusion, the results of the thesis are evaluated.

Physiological Data to Analyze and Improve the User Experience
Štěpánek, Daniel ; Beran, Vítězslav (referee) ; Materna, Zdeněk (advisor)
The goal of this thesis is to obtain dataset of physiological data for user emotions in order to analyze and improve human-computer interaction. This paper proposes of the use Empatica wristband to capture physiological data and Python for data processing. After evaluation, 94 % of intact data was obtained from the expected number of samples. Based on the obtained data, it is possible to better analyze the user experience and thus improve it.

Heart rate measurement
Danielová, Tereza ; Veselý, Petr (referee) ; Chmelař, Milan (advisor)
Bachelor’s thesis deals with measurement of heart rate, its monitoring and evaluation which is relevant for the diagnosis of cardiac dysfunction. The first part describes the anatomy of heart and its activity. In the next part is further mention of the heart rhythm and its disorders. In the bachelor thesis is described several methods that are used in the evaluation of heart rate. The next part deals with the description of the device for scanning heart rate and description of the virtual instruments in LabVIEW.

Indoor Detection of People Based on Vital Sign Sensing
Plaček, Dan ; Heidari, Mona (referee) ; Drahanský, Martin (advisor)
V dnešní době chytrých domácností a velkého důrazu kladeného na ochranu dat, je žádoucí provádět detekci přítomnosti člověka a také jeho zdravotního stavu anonymně, a to za pomoci jeho vitálních funkcí. Cílem této práce je provést detekci osob na základě jejich vitálních funkcí, konkrétně tepu a dechu. Za tímto účelem je navržen algoritmický přístup a následně je implementováno řešení. Tep a dech je snímán UWB a FMCW radarem, následně jsou získaná data zpracována a zmíněné vitální funkce jsou extrahovány. V práci je také představeno experimentální měření a jeho výsledky.

Meter of pulse frequency variability
Starzyczny, Radek ; Lutera, Ondřej (referee) ; Strašil, Ivo (advisor)
The aim of this thesis was to design and construct an autonomous module for receiving and processing HRV (Heart Rate Variability). The device is made as an extension board for development kit STM32. For receiving HR signal is used sensor RMCM-01. The device allow calculate and display the heart rate and its variability and some more parameters from collected data.

Heart Rate Variability Measurement Device
Süss, Ivo ; Číž, Radim (referee) ; Strašil, Ivo (advisor)
The aim of this thesis was to develop a device that will receive the signal from sporttester belt and then that signal will be processed. The meter is based on development kit STM32 Primer 2. To receive signals from sporttester belts uses sensor RMCM-01 Polar. The meter allows measurement of parameters of heart variability, recording on a memory card and work with the measured data from the memory card.

The heartbeat counter
Malínský, Zdeněk ; Dlouhý, Jiří (referee) ; Švrček, Martin (advisor)
Heart rate variability belongs to basic and most frequently interpretation of physiologic statement in medicine. The pulse rate serves as an indicator of the heart activity. The subject of this diploma thesis is projection of the heartbeat counter. The work describes electrocardiograph and separated waves, ways of calculation heart rate, characteristics mechanism for measuring and other necessary information about heart rate measuring. This master thesis fixates on heart rate-calculation from including R-R intervals. Here is described whole project of heartbeat counter, properties of separated blocks and calculation of useful parameters. Further there is noted software resolution for the microcontroller and program for the calculation of heart rate frequency including unwinding signal preprocessing and detection of separated QRS complexes. The products of this diploma thesis are the circuit including the board circuit and codes of separated programs.

Detection of atrial fibrillation in long-term ECG records
Imramovská, Klára ; Kozumplík, Jiří (referee) ; Maršánová, Lucie (advisor)
The thesis deals with problems of automatic detection of atrial fibrillation in long-term ECG records. The preface of the theoretical part describes the electrophysiology of the heart and the principle of atrial fibrillation. Furthermore, it introduces methods of automatic detection of atrial fibrillation. In the practical part a method which uses the symbolic dynamics and a calculation of Shannon entropy is implemented in the MATLAB software environment. The method is tested on signals from the MIT-BIH Atrial Fibrillation Database and the Long-Term AF Database. Lastly, the accuracy of the classification is compared with methods described in different papers.
