Intracardiac electrograms (EGM) in Cardiac Navigation Systems (CNS) and in Electrocardiographic Imaging provide relevant information on the arrhythmia mechanism for supporting ablation. In our previous work, we proposed Manifold Harmonics Analysis (MHA) for establishing the spatial sampling rate in ElectroAnatomical Maps (EAM) accounting for anatomical and bioelectrical features (e.g., voltage or...
The spatiotemporal sampling of electrograms (EGM) yielding 3-D maps of cardiac features (activation, organization, amplitude) in Cardiac Navigation System (CNS) for arrhythmia ablation, is currently driven by heuristic considerations. Manifold Harmonic Analysis (MHA) allows spectral analysis of multidimensional structures in computer graphics, however, its connection to Sampling Theory has not been...
