Figure 8

Stability diagram, showing regions in which reentry occurs in the R-\({p}_{f}\) plane when we stimulate a medium with a clump of fibroblasts by using the high-frequency TP stimulation protocol. We find no reentry in the outermost, dark-blue region of the R-\({p}_{f}\) plane. The different colours indicate the number of times we obtain reentry in the 10 simulations (for each pair of values of \({p}_{f}\) and R, we perform 10 simulations for 10 different realizations of the fibroblast distribution inside the clump). We use the TP-pacing protocol (see text) with PCL = 152 ms. The colours indicate the total number of reentries we obtain in our simulations for 10 different realizations of the random distribution of fibroblasts.
