Scalars (mean±SD) for the population of cells with G_Kr-G_CaL co-expression. (A) 50 cells with the longest APD₉₀ values and no EAD with increasing % I_Kr block. (B) cells with EADs with increasing % I_Kr block. The G_CaL and G_Kr scalars are highlighted in yellow. (C) APD₉₀ values (left axis) for the highest (red) and lowest (blue) quartile of cells according to baseline G_CaL scalar. The continuous lines show the mean value and shaded area shows ±1 SD. The percentage of EADs in each quartile is shown as columns (see axis on right side of graph). The corresponding plots for the population of cells with independent G_Kr-G_CaL scalars are show in Supplementary material online, Figure S7.
