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…
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…
An ionically based mapping model with memory for cardiac restitution
David G. Schaeffer, John W. Cain, Daniel J. Gauthier +4
Many features of the sequence of action potentials produced by repeated stimulation of a cardiac patch can be modeled by a 1D mapping, but not the full behavior observed in the res…
