Figure 7 Values of intra-ventricular asynchrony (intraVA) (n = 5), inter-ventricular asynchrony (interVA) (n = 12), and QRS duration (n = 12) at a maximum increase of left ventricular (LV) maximum rate of increase in pressure (dP/dtmax) (left column) and stroke work (SW) (right column). The mean ± SD of pre-left bundle branch block (LBBB) (C) and post-LBBB (LBBB) values are indicated by the patterned bars (one-way analysis of variance followed by Tukey post hoc testing for C vs. LBBB; * p < 0.05 vs. LBBB and C, respectively). The results for anterior and posterior wall pacing were comparable to those for lateral wall pacing.
