TABLE V.

The average endocardium segment strains (%) at ES in the four steady states. S₁ to S₁₂ are the RVFW segments. ${\overline{M}}_{\mathrm{apx}}$, ${\overline{M}}_{\mathrm{mid}}$, and ${\overline{M}}_{\mathrm{bas}}$ are the mean strain of all apical, mid, and basal segments. BSL, RV, RVA, and RVOT stand for baseline, RV pacing, RV apex pacing, and RVOT pacing, respectively.
