A phase defect framework for the analysis of cardiac arrhythmia patterns
Louise Arno, Jan Quan, Nhan T. Nguyen +3
During cardiac arrhythmias, dynamical patterns of electrical activation form and evolve, which are of interest to understand and cure heart rhythm disorders. The analysis of these…
Rate-dependent propagation of cardiac action potentials in a one-dimensional fiber
John W. Cain, Elena G. Tolkacheva, David G. Schaeffer +1
Action potential duration (APD) restitution, which relates APD to the preceding diastolic interval (DI), is a useful tool for predicting the onset of abnormal cardiac rhythms. Howe…
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…
Control of cardiac alternans in a mapping model with memory
Elena Tolkacheva, Monica M. Romeo, Daniel J. Gauthier
We investigate a map-based model of paced cardiac muscle in the presence of closed-loop feedback control. The model relates the duration of an action potential to the preceding dia…
