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.
