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.

Detection and filtering of ECG signals
Princ, Martin ; Kozumplík, Jiří (referee) ; Provazník, Ivo (advisor)
The aim of this thesis is to provide insight into certain elementary methods/ways of electrocardiographical signals filtration. Also, the thesis aims to introduce different techniques of detecting the EKG signal waves. The first part of the work analyses the theory of heart, electrical processes in heart, and the EKG signals systems. Further, the elementary methods of filtration and QRS detection are introduced.In the second part, the thesis analyses the BIOPAC student Lab system and presents simple methods of measuring the static EKG. The measure data results are then processed using the MATLAB program, and they are further used to demonstrate and practice the elementary methods of EKG filtration and QRS complex detection. Operation detectors QRS test on database EKG signal.
