Figure 5 Changes in left ventricular (LV) maximum rate of increase in pressure (dP/dtmax) relative to baseline left bundle branch block (LBBB) as a function of the (A and C) paced atrioventricular (AV) delay and (B and D) excitation time difference between LV and right ventricular (TVV) for two experiments during LV apex and LV lateral wall pacing. The results for anterior and posterior wall pacing were comparable to those for lateral wall pacing.
