From: Echo-driven V-V optimization determines clinical improvement in non responders to cardiac resynchronization treatment

Figure 6

Figure shows tissue velocity maps obtained at baseline (A and C), during LV pre-excitation of 20 ms (B and D) and during LV pre-excitation of 40 ms (C and E) in apical 4 and 3 chamber views. Progressive decrease in septolateral wall delay (shown in B and C compared to A by white lines) and in septoposterior wall delay (shown in D and E compared to C by dotted white lines) occurred with progressively increasing LV pre-excitation. In addition progressive LV pre-excitation led to improvement in septoposterior wall delay in diastole (horizontal white lines, C-E).
