Period-doubling bifurcation to alternans in paced-cardiac tissue: Crossover from smooth to border-collision characteristics

We investigate, both experimentally and theoretically, the period-doubling bifurcation to alternans in heart tissue. Previously, this phenomenon has been modeled with either smooth or border-collision dynamics. Using a modification of existing experimental techniques, we find a hybrid behavior: very...
