Heart rate meter
Šeda, Jan ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The aim of the Bachelor thesis is summary of pulse measurement facilities. Heart pulse has been one of the basic measurable quantity in medical science for thousands of years. The basic quality of the given value is accuracy. The analyse of necessity of accuracy in methods for medical practice and diagnostic is the second point of the thesis. The third and most crucial point is heart pulse meter itself – it will be described in terms of mechanics, electrics and software. System based on optical measurement has been chosen in semestral project. Furthermore, accuracy of designed meter will be tested.

Cardiotachometer
Máca, Kamil ; Číž, Radim (referee) ; Chmelař, Milan (advisor)
This masters thesis describes possibilities of a heart rate measuring. Several methods of measuring will be discussed. The primary objective of this paper is to design battery powered cardiotachometr with a range of 30-240 beats/min and a low battery indication. Cardiotachometer uses the R waves detector to measure heart rate. This thesis is focused on creation of the block diagram, electrical circuit, printed circuit and calculation of electronic device used in cardiotachometers.

Sleep stage classification based on HRV signals
Schlorová, Hana ; Kubičková, Alena (referee) ; Kozumplík, Jiří (advisor)
The most common method for scoring of sleep stages is the evaluation by EEG. This work utilizes ECG signal to the comparable evaluation of sleep. It summarizes the methods of presentation and assessment of heart rate variability (HRV) and describes the whole algorithm of calculation and presentation of this signal using Lorenz plot. This work also focuses on evaluation of Lorentz plots and parametrs quantifying variability of samples in maps. It seeks to draw the conclusion of sleep stages from their waveform.

External pacemaker
Lank, Petr ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
This master´s thesis deals with the problem of heart stimulation by using external pacemaker. Such external pacemaker is used for a short – time stimulation of patient to overcome the time before the implantation of such apparatus. The master´s thesis informs about the basic function of heart and possible heart disorders which are treated by pacemaker. Great deal of master´s thesis is devoted to the design of external pacemaker wiring. This section describes the possibilities of controlling the pacemaker, circuits for detection R-R interval, a design of output circuit eith regard to required of stimulation and pacemaker feeding. The program Pspice was used to check the functional appropriateness of designed circuits and it was successively simulated in a non - soldering field.
