Bifurcations in the Echebarria-Karma Modulation Equation for Cardiac Alternans in One Dimension
<p>While alternans in a single cardiac cell appears through a simple</p><p>period-doubling bifurcation, in extended tissue the exact nature</p><p>of the bifurcation is unclear. In particular, the phase of</p><p>alternans can exhibit wave-like spatial dependence, either</p><p>stationary or …

Metabifurcation analysis of a phenomenological ventricular cell model
… directly; however, it has been shown that cardiac alternans is closely related to arrhythmia[35]. Therefore, predicting alternans could be the _rst step in preventing arrhythmia. Fenton and Karma(1998)[10] came up with the Fenton-Karma model (the F-K model) with three variables and 13 …
