Mapování elektrické srdeční aktivity

Abstract

This thesis focuses on the recording and visualization of cardiac electrical activity using three key methods: electrocardiography (ECG), vectorcardiography (VCG), and body surface potential mapping (BSPM). The theoretical section introduces the principles of bioelectrical signal propagation through cardiac tissue, the distribution of potentials on the body surface, and the specific measurement systems used. The experimental part includes signal acquisition from healthy volunteers, the application of various electrode systems, and subsequent data processing in MATLAB. The primary goal is to compare the diagnostic and informational value of these methods, interpret the collected data in the context of spatial cardiac activity, and generate illustrative visualizations. Emphasis is placed on non-invasive approaches, inter-individual signal variability, and the future potential of BSPM in both clinical diagnostics and research.
