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.

Heart rate changes during walking and running
Smolinský, Dominik ; Kozumplík, Jiří (referee) ; Kolářová, Jana (advisor)
This bachelor thesis is concerned with monitoring dynamic changes in heart rate during walking and running. The heart rate is calculated from the QRS complexes of the ECG signal. The aim of this thesis is to summarize the theoretical knowledge and then make measurements of individuals from 2 groups, fit athletes and less fit athletes. Thus, the theoretical part is discussed first, where all the information regarding the cardiovascular system, heart rate and HRV are described. The second part of the thesis is practical and deals with specific measurements, their processing and statistic analysis. It also describes the basic equipment and measurement protocol.
