Characterizing Spatial Dynamics of Bifurcation to Alternans in Isolated Whole Rabbit Hearts Based on Alternate Pacing

Figure 2

(a) Representative 2D alternans maps for SS BCLs showing the local onset of alternans at BCL_start (red box). Two prior BCLs, BCL_prior and BCL_far, are also shown (green and blue boxes). (b) 2D alternans maps induced by perturbations at BCL_prior and BCL_far. Color bar represents the amplitude of alternans.
