Longitudinal strain and time to peak strain “bulls eye” plots for baseline, CSP and LOT-CRT (left bundle branch-optimized cardiac resynchronization therapy) in the same patient. In the strain bull's eye and myocardial work analysis, the red areas represent regions with normal longitudinal strain, while the pink areas indicate regions with impaired longitudinal strain. For myocardial work, blue values indicate the shortest times to maximum deformation, red values indicate the longest times, and green values represent normal times
