FIGURE. The automatic annotation of LAVAs depending on the accurate identification of fragmented potentials, late potentials and double potentials. Accurate annotation is depicted by a tick and poor annotation by a minus. Fragmented potentials were accurately annotated regardless of wavefront direction or scar location. Late potentials were accurately annotated during sinus rhythm and in lateral LV scar but this accuracy was reduced during RV pacing and in LV septal, LV apical and epicardial scar. Double potentials were accurately annotated regardless of wavefront direction and in LV scar but this accuracy was reduced in RV and epicardial scar.
