Changes in pulmonary function and cardiac activity during reflex rolling stimulation according to Vojta
Charvátová, Zuzana ; Nováková, Tereza (advisor) ; Martínek, Milan (referee)
Author: Zuzana Charvátová Title: Changes in pulmonary function and cardiac activity during reflex rolling stimulation according to Vojta Objectives: The aim of this study is to evaluate accompanying non-locomotive manifestations within the comprehensive response to stimulation of trigger zones from the concept of reflex locomotion according to Professor Vojta, which are a reflection of the function of the autonomic nervous system. Changes in respiratory parameters and changes in cardiac activity have been selected from these manifestations. Methods: The research was conducted on 26 healthy adult women aged 19-25 years. Reflex rolling according to Vojta from the supine position (RO - 1st phase) was chosen. Pressure stimulation was applied from the left chest trigger zone between the 6th and 7th rib for 10 minutes. Each subject also underwent apparent (sham) stimulation in the same position (RO - 1st phase), lasting 10 minutes, but on the right side of the chest between the 2nd and 3rd rib. Due to the possible lingering effect of pressure stimulation during VRL, sham stimulation was always preceded by experimental stimulation. A 10-minute break was taken between the two cycles. Data for the analysis of changes in lung function were obtained by spirometric measurements of FVC, FEV1, and PEF before...

Reccurence plot for heart rate variability analysis
Franěk, Pavel ; Čmiel, Vratislav (referee) ; Janoušek, Oto (advisor)
The aim of this thesis is to describe the variability of cardiac rhythm and familiarity with the methods of the analysis, ie by monitoring changes in heart rhythm electrogram signal recording and using the methods in the time domain using recurrent diagram. The work describes the quantification of the methods and possibilities of quantifiers in the evaluation of heart rate variability analysis. It also describes the clinical significance of heart rate variability and diagnostic capabilities changes of heart rate variability caused by ischemic heart disease. The practical part describes how to create applications in Matlab to calculate the quantifiers analysis of heart rate variability in the time domain using recurrent diagram. The calculation was made of the positions R wave elektrogram signal isolated rabbit hearts. The calculated values of quantifiers both methods were statistically evaluated and discussed.

Analysis of heart rate variability in animal models
Řehořková, Iveta ; Ronzhina, Marina (referee) ; Kolářová, Jana (advisor)
This paper deals with the analysis of heart rate variability (HRV) in animal models. The first part discusses, the basic information concerning the ECG, both in humans and in individual laboratory animals. This is followed by an introduction to the topic of heart rate variability, a description of methods for its determination and the effects of pathologies on HRV values. Prior to the practical section, the methods of ECG acquisition in animal models are discussed, and the function of the perfusion model used in capturing data for this work is also described in detail. The last part deals with the analysis of HRV provided data, performed in Matlab environment and an evaluation of the chosen methods.

Heart rate variability analysis
Potočňák, Tomáš ; Kolářová, Jana (referee) ; Ronzhina, Marina (advisor)
The topic of this bachelor’s thesis is online analysis the heart rate variability (HRV) using the programming environment LabVIEW 2010. The main part of proposed software is processing the input signal obtained by R-peak sensor developed by Vernier Company, and its time, frequency and nonlinear analysis. Used components and instruction for creating software are represented in user manual. Results of the tested program are shown in the figures.

Measurement of cardiovascular parameters
Kratochvíla, Jiří ; Čmiel, Vratislav (referee) ; Kolářová, Jana (advisor)
The aim of the bachelor’s thesis is to get acquainted with the measurement of cardiovascular parameters, to realize the measurment of these parameters, to analyze them, show the statistic procedure of verifying hypotheses in this spere and finally the presentation of measured data including automatical detection of the heart rate from ECG signal in created program in Guide of Matlab system. On the basis of the theory was done the measurment on own suggestion with the Biopac system and with the quicksilver tonomether. The parameters, that were measured on the group of five people: ECG, blood pressure and the pulse frequency before and after the load. After the data processing was done the statistic analysis, the aim of this analysis was to show the procedure of verifying hypothesis, if and how are these measured parameters of cardiovascular system changing. After that the measured data were transported into Matlab system. The presentation of measured data (created program) contains the time domain and spectral analyses (using Fourier transform) of ECG signal, automatical detection of the heart rate from ECG signal, analysis of the heart rate variability (HRV) – tachogram together with detailed analysis of HRV spectra (spectra of heart rate variability – relating with parasympathetic and sympathetic activity), that are using in clinical practice too, just as the other measured parametres of the cardiovascular system.
