ECGI imaged many activation patterns of commonly multiple wavelets (92%), with pulmonary vein (69%) and non-pulmonary vein (62%) trigger sites. Rotor activity was seen rarely (15%). AF complexity increased with longer clinical history of AF, though the degree of complexity of nonparoxysmal AF varied and overlapped. ECGI offers a way to identify unique epicardial activation patterns of AF in a patient-specific manner. The results are consistent with contemporary animal models of AF mechanisms and highlight the coexistence of a variety of mechanisms among patients.
