Figure 6 Stroke work (SW) (top) and +dP/dt_MAX (bottom) at the RV pacing site (RVA, RVS, or RVF), resulting in maximum (MAX RV) and minimum (MIN RV) stroke work or +dP/dt_MAX compared with stroke work measured during control (AAI). The site of maximal stroke work or +dP/dt_MAX was not different from AAI. Thus, RV pacing does not necessitate attenuated hemodynamics. However, the optimal RV site varied between patients. *p < 0.05 versus AAI, (RM ANOVA with Student-Neuman-Keuls post-hoc comparison). Other abbreviations as in Figures 1 and 2.
