Equivalent dipole sources to estimate the influence of extracellular myocardial anisotropy in thin-walled cardiac forward models
(Elsevier, 2017)The extracellular domain of the heart is anisotropic, which affects volume conduction and therefore body surface potentials. This paper tests the hypothesis that when wall thickness is sufficiently small (such as in the atria), the effect of extracellular ... -
A simple analytical model of action potential duration profile in electrotonically-coupled cells
(Elsevier, 2016)Electrotonic interactions between cardiac cells modulate the dispersion of action potential duration (APD). This paper provides a complete mathematical analysis of a simple model of exponential-shaped repolarization in a network of electrotonically-coupled ... -
Steady-state solutions in mathematical models of atrial cell electrophysiology and their stability
(Elsevier, 2006-11-10)The steady states of the Fenton–Karma, the Courtemanche and the Nygren cell models were studied by determining the fixed points of the dynamical system describing their cell kinetics. The linear stability of the fixed points was investigated, as well ...
