Spatio-temporal cardiac pacing sites localization and time varying pericardium potential maps projection using ECG precordial leads and a single moving dipole model

TL;DRAbstract

A novel non-invasive method for the spatiotemporal localization of the sites of strongest cardiac activity, and for the creation of time varying Pericardium Potential Maps (PPM), with the use of patients' ECG precordial leads, is proposed in this Thesis study. Compared to previous studies, which analyze electrocardiograms in either time domain or spatial domain, the proposed method has the advantage of a simultaneous spatiotemporal electrocardiograph analysis and a 3-D visualization of pericardium potentials maps, as well as, the pericardium surface polarization patterns during the cardiac cycle. The spatial properties added to the electrocardiogram allow for the analysis of specific regions inside the human heart where potential cardiac malignancies are suspected to occur. In this thesis, the concept of electrocardiography was extended using advanced bioelectromagnetism theory. The propossed MATLAB-based software makes use of the single-moving dipole model, optimized in location and m
