Pacing locations. Endocardial pacing locations are in red and epicardial pacing locations in black. Distances from the scar surface are indicated by the white point cloud. Epicardial (epi) and endocardial (endo) surfaces and the transmural action potential duration (APD) gradient are indicated by the black arrow.A: Patient-specific model. Locations were chosen at (from right to left) 0.2, 0.5, 1.5, 2.5, and 3.5 cm from the scar surface. B: Idealized model. Locations were chosen at 0.2 and 3.5 cm from the scar surface.
