Cardiac Alternans Arising from an Unfolded Border-Collision Bifurcation
Xiaopeng Zhao, David G. Schaeffer, Carolyn M. Berger +2
Following an electrical stimulus, the transmembrane voltage of cardiac tissue rises rapidly and remains at a constant value before returning to the resting value, a phenomenon know…
Small-Signal Amplification of Period-Doubling Bifurcations in Smooth Iterated Maps
Xiaopeng Zhao, David G. Schaeffer, Carolyn M. Berger +1
Various authors have shown that, near the onset of a period-doubling bifurcation, small perturbations in the control parameter may result in much larger disturbances in the respons…
Evidence for an unfolded border-collision bifurcation in paced cardiac tissue
Carolyn M. Berger, Xiaopeng Zhao, David G. Schaeffer +3
We investigate, both experimentally and theoretically, the bifurcation to alternans in heart tissue. Previously, this phenomenon has been modeled either as a smooth or as border-co…
