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

Figure 6

Spatial correlation of alternans induced by perturbation (at  ms) with bifurcation characteristics. (a) 2D bifurcation map calculated at BCLprior (see Figure 3(c)). (b) 2D alternans map at  ms calculated at BCLprior (see Figure 2(b)). (c) Spatial correlation between these two maps. Average % of smooth, border-collision, and undetermined bifurcations from all experiments are shown for (d) BCLprior and (e) BCLfar. indicates significance of between smooth and border-collision bifurcations. # indicates significance of between smooth and undetermined bifurcations.
