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.

Cardiorenal syndrome and detection of early changes in kidney and myocardial function including determination of risk factors in asymptomatic patients with arterial hypertension The presented thesis aimed at determining the possibility to identify changes related to cardiorenal syndrome development in patients with satisfactorily compensated arterial hypertension. In the group of 96 patients within the period of 2 years we repeatedly examined 24-hour blood pressure monitoring, ultrasound imaging (echocardiography, renal resistive index), a set of laboratory analyses of cardiac and renal functions, and analyzed the relations between the blood pressure values and the monitored cardiac and renal parameters. In the preliminary examination we discovered an association between the 24-hour diastolic pressure and glomerular filtration. The main finding based on the follow-up monitoring was the rise of the renal resistive index and its significant correlation with the ratio of diastolic to systolic pressures without any relation to changes in anti-hypertension medication. By contrast, we did not identify any significant changes when evaluating the cardiac parameters. The results of the research emphasize the importance of monitoring not just systolic, but also diastolic blood pressure, to recognize a...
