Analýza variability srdečního rytmu s využitím PPG záznamů

Abstract

The Bachelor's thesis is focused on heart rate variability and its analysis using PPG records. This thesis describes, explains and compares methods of measuring heart rate using electrocardiographic (ECG) and photoplethysmographic (PPG) recordings. In the beginning of thesis, the theory of the cardiovascular system, heart rate variability and acquaintance with the measurement of ECG recordings is described. At the end of the theoretical part, the measurement of PPG records is explained with the possibilities of their subsequent processing for HRV analysis. The practical part deals with data acquisition on volunteers, later the design of an algorithm for signal preprocessing, calculation of selected HRV parameters and finally statistical evaluation of success and discussion of results.
