Left: epicardial contours colour-coded for epicardial fat thickness according to bar, together with coronary arteries in a modified right anterior oblique view, right: epicardial bipolar voltage maps from the same two patients. Integration of epicardial fat images together with abnormal electrogram characteristics allows for classification of electograms; (A) low-voltage electrogram with late potential in area without fat is due to scar (B) low voltage due to fat (C) low voltage, fragmented electrogram due to scar potentially attenuated due to fat (D) very low-voltage electrogram due to fat.
