Example of a positive case (upper panel) and a negative case (lower panel) of mechanical dispersion (83 and 26 ms, respectively) as a predictor for ventricular arrhythmia or all-cause mortality. (left) Bullseye for regional mapping of the delay time in mechanical contraction. Non-moving segments and manually excluded slices are depicted in gray. (right) Late gadolinium enhancement MRI for viability, 3 short-axis slices. (upper panel) Patient of 41 years old, LVEF 26%, total scar mass, 57 g. Appropriate ICD therapy (shock) 5 months after MRI. (lower panel) Patient of 52 years of, LVEF 25%, total scar mass, 63 g. During the follow-up of 40 months, no arrhythmic event occurred.
