Chronotherapy as a new trend in the treatment of hypertension
Pafková, Patrícia ; Sumová, Alena (advisor) ; Alánová, Petra (referee)
Hypertension is still the leading cause of death and cardiovascular morbidity worldwide, but its long-term control remains unsatisfactory. Blood pressure is subject to certain variability during 24 hours, when its values are 10-20% lower at night than during the day. Due to the new knowledge that the circadian rhythm exists in almost all organ systems, interest in chronotherapy as a new trend in treatment is growing. This bachelor's thesis points out the importance of respecting circadian rhythms and includes current knowledge about chronotherapy of hypertension, together with an analysis of its benefits in the treatment of high blood pressure. Keywords: hypertension, circadian rhytm, antihypertensives, chronotherapy, blood pressure

Laboratory exercise using Vernier systems
Kubová, Dominika ; Mézl, Martin (referee) ; Králík, Martin (advisor)
The aim of this thesis is to design a measurement procedure in the LabVIEW development environment for three laboratory exercises using an ECG sensor, a blood pressure sensor and a spirometer from Vernier. In the theoretical part, the physiological introduction, the problems of the given devices and measurement methods are described. The practical part focuses on the development and verification of the proposed measurement protocols, which are attached as appendices to the thesis. It also includes support files for the exercises, including scripts for basic data acquisition and calibration. These materials are intended to serve as teaching tools enabling effective training and understanding of measurement methods in medical diagnostics.

Physiocrate: A SignalPlant Toolbox for Respiratory, Blood Pressure and EMG Signal Analysis
Nejedlý, Petr ; Virgala, Jan
The paper presented here describes the SignalPlant library for analysis of physiological signals. This library contains plugins for analysis of continuous blood pressure (BP), respiratory signals (RESP) and electromyographic signals (EMG). Its principal advantages are real-time previews of results, ease of use and a multi-thread approach. The library is available free and open- source under an MIT license as part of the SignalPlant project at https://signalplant.codeplex.com.

Medical standing devices
Vadják, Šimon ; Ronzhina, Marina (referee) ; Kolářová, Jana (advisor)
This bachelor‘s thesis deals with patient verticalization and medical standing devices, which we use for this purpose. These findings are particularly important for rehabilitation and nursing care and also for the development of new standing devices. The bachelor‘s thesis describes the basic con¬cepts of human motor skills, the effect of changing position on the human organism, an overview of medical standing devices and their comparison. Thesis deals with comparison of the technical pa¬rameters of two standing devices more closely, standing device BALANCE Trainer and STOJ. The final part is devoted to measuring blood pressure using the noninvasive, continuous method of measuring at a group of wheelchair users during verticalization. I created a program with a graphical interface which allows measured data to load, display and measure, in numerical compu-ting environment MATLAB (version 7.9.0-R2009B). The results were statistically tested in the same numerical computing environment.

Influence of postural change to the pulse wave velocity in the upper limb
Sakmárová, Klára ; Hrušková, Jana (referee) ; Svačinová, Jana (advisor)
This thesis is devoted to the topic of pulse wave velocity in the upper limb based on changes in body position. The work includes a literature search from the mentioned area, where it focuses mainly on the cardiovascular system, the pulse wave, its propagation in the human body, the clinical significance of the pulse wave and the factors that affect it. Pulse wave examination has now become an important part of the preclinical diagnosis of atherosclerosis or arterial stiffness. Examination of the pulse wave velocity as well as examination of the vascular system as part of early diagnosis is highly desirable for the stratification of cardiovascular diseases and subsequent mortality. In this work we will evaluate the speed of the pulse wave based on the time distance between the oscillation R on the ECG and the passage of the pulse wave under the pressure sensor located on the finger. In the MATLAB, a software solution of selected procedures for ECG measurement and blood pressure recording heart rate after heart rate is made. The measured values on a group of volunteers are statistically processed and subsequently discussed.

Analysis of measured parameters of the cardiovascular system
Lysoň, Jakub ; Vítek, Martin (referee) ; Kratochvíla, Jiří (advisor)
This bachelor thesis talks about the measurement of heart electrical activity by twelve lead ECG. The diagnostic system Biopac is used for measurement, featured by the computer program Acqknowledge. The own authentic method is designed to detect effect of load on increasing in blood pressure and heartbeat. Using a statistical procedure for testing hypotheses in this area the measurement results will be evaluated. For the analysis of measured data in time and frequency domain was used program Matlab, in which the measured results were imported. It was created functions that are implemented in an medium of Guide to the graphic design program.

Processing of a continual blood pressure signal
Svobodová, Ivana ; Soukup, Ladislav (referee) ; Vondra, Vlastimil (advisor)
Bachelor thesis contains a general description of the blood pressure phenomenon and its importance and also deals with diseases, such as hypotension and hypertension. The work also includes a literature review of blood pressure measuring methods. Closely are discussed the non-invasive methods. The result of the work is also a unique program designed in Matlab, which is developed for signal processing of continuous blood pressure measurement for detection of SBP and DBP and MAP, pulse after pulse. To verify the functionality of the program, the further implementation was carried out in GUI. In conclusion, the obtained data are beeing analyzed statistically.

Causal interaction analysis of cardiovascular signals
Tiurina, Mariia ; Kolářová, Jana (referee) ; Svačinová, Jana (advisor)
Application of the non-invasive methods to detection of the baroreflex sensitivity is a correct way to evaluate the functions of cardiovascular system. This master’s thesis describes the theoretical informations about the problem of baroreflex sensitivity from anatomical, patalogical and clinical views. Theoretical knowledges are foundation for mathematical description of some methods to detection of baroreflx sensitivity in time, frequency and information dimensions. In the practical part of the master’s theses are presented two methods of BRS detection – sequence method based on finding the specific sequences of time series signals and method of application bivariante autoregressive model. Both of methods are implemented in MATLAB. The results of testing data on real data are discussed.
