Table 5.

Biomarkers corresponding to virtual CRT configurations varying left lead position. See Fig. 7 for the different locations of the left electrode. For CRT scenarios we indicate the percentage of variation of ${dP/dt|}_{\text{max}}$, SV and SW with respect to the pre-operative case, whereas for EF we indicate the absolute changes. P2, P3, P4: non-fibrotic cases; P6, P8, P11: fibrotic cases
