Scanning a analysing of heart electrical activity and blood pressure before and after the load
Vích, Daniel ; Kolářová, Jana (referee) ; Kratochvíla, Jiří (advisor)
The aim of bachelor’s thesis is familiarization with anatomy and physiology of heart, with setting to electrical activity, scanning EKG before and after the load with Biopac system, scanning of blood pressure before and after the load with auscultation, statistical analysis of acquired data and presentation of measured data in graphical interface Guide of Matlab system. According to the protocol of measurement, scanning of heart electrical activity with the Biopac system, and scanning of blood pressure, with auscultation, was realized before and after the load. Measured data was statistically analyzed with t-test to verify hypothesis, that there is an influence of the load on the watched parameters, and to show the process of statistical verification. Application of this method assumes normal distribution of data, that’s why data was at first tested by Chi-squared and Kolmogorov-Smirnov test to verify their normal distribution. In the next step data was imported into Matlab system. The presentation of measured data is realized in graphic interface Guide. The program contains time domain and spectral analysis, automatic detection of heart rate and analysis of heart rate variability.

Blood presure measurement in LabVIEW
Čermák, Marek ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
The aim of this work is to design and create a product for automated measurement of blood pressure by auscultatory method by using a computer. Thesis contains a description of the blood pressure, also there are explained ways of its monitoring, basic rules for its measurement and the methods by which it is possible to measure blood pressure. In the practical part is described measuring system serving to measuring blood pressure by auscultatory method using a computer. There is also shown a design and realization of microphone preamplifier. The work also includes a description of a computer program created in LabVIEW, which is used to measure by using a previously described system. In the end is evaluated the accuracy of the whole meter.
