ECG signal generator
Štohanzlová, Petra ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
This work deals with the generation of ECG signal and options how to generate it using the LabVIEW program. On the basis of the studied methods of describing signal was chosen method making use of the similarity of the sections of ECG curve and the sinus respectively triangular pattern. This method was subsequently implemented in the LabVIEW environment. Created virtual instrument generates ECG signal in given heart rate and adjustable amplitude of waves. It is also possible to choose between 12 standard leads, to realize several failures of cardiac activity and various disturbance signals can be added to the signal. Signal can be sent to output or saved as a text file in real time in the specified format.

Software ECG generator
Hendrych, Marek ; Smital, Lukáš (referee) ; Vítek, Martin (advisor)
The diploma thesis deals the cretion of the ECG signal and its potential morphology. A signal is generated using a program that is created in MATLAB. On the basis of these methods of describing the signal, was chosen method, based on the similarity of ECG with sinus respectively. triangular pattern. Generated by the program can draw the ECG signal by assignment of pulse rate, lenght of the signal, sampling rate and modifications of the waves and oscillations. One or more predefined noise can be added to the signal. Generated signal is possible to save to the format that supports program MATLAB.

New Approaches in Cardiac Optical Mapping
Švrček, Martin ; Kizek, René (referee) ; Sovka, Pavel (referee) ; Provazník, Ivo (advisor)
This dissertation deals with new approaches in cardiac optical mapping. The principle of cardiac optical mapping as well as the current research in this field was described. The new measurement system was developed and its characteristics presented. The system design allows epicardial and endocardial mapping, employing new ratiometric techniques in 2D acquisition and simultaneous electrical and optical mapping. The measured characteristics of fluorescent dye di-4-ANEPPSS were presented. The relation between movement and consequent motion artifacts is well described. Several new approaches in signal processing were proposed, including new ratiometry technique and using image registration to suppress motion artifacts. The algorithm for elastic image registration of optical signals and innovative method for verification of registration process were presented. Application of all proposed approaches and its results are included and discussed.
