(a) (left) Shock-end V_m distribution (SS 20 V) within complex model for the case where the reduced conductivity of the lumen wall (Fig. 1(d)) has not been represented (i.e. $g_e^{lum}=1.0$ S/m). (right) Difference map of V_m distribution for normal case ($g_e^{lum}=1.0$ S/m, left panel) minus that of experimentally-derived case ($g_e^{lum}=0.010$ S/m), with selected region in vicinity of large vessel highlighted. (b) Difference maps of V_m distributions (SS 20 V) for varying $g_e^{lum}$ conductivities minus V_m distribution of experimentally-derived case (Fig. 5), with selected region in vicinity of large vessel highlighted.
