(A) An active contour applied to a strain matrix automatically depicts the region of late mechanical activation (red arrow). (B) Correlation plot between DENSE mechanical activation time and electrical activation time (QLV) for segments where the CRT LV lead was placed in a region without scar. (C) Correlation plot between DENSE mechanical activation time and QLV for segments where the CRT LV lead was placed in a region with scar
