Derived from the pioneer ionic Hodgkin-Huxley model and due to its simplicity and richness from a point view of nonlinear dynamics, the FitzHugh-Nagumo model (FHN) is one of the most successful simplified neuron / cardiac cell model. There exist many variations of the original FHN model. Though these FHN type models help to enrich the dynamics of the FHN model, the parameters used in these models...
The aim of this work is to study the feasibility of reconstruction mathematical model of cardiac tissue from intracellular recordings. It is studied using simulated data and the presented method is applied to the Aliev-Panfilov model. A dissociated scheme is proposed and the estimation of some parameters is investigated in case of ideal or noisy data. The influence of the number and distribution of...
Recent studies showed that spiral waves could be involved in cardiac fibrillation. Changing the dynamics of spiral waves and stoping them by electric stimulations provide a potential way of defibrillation. However, electric stimulation could bring some serious problems to patient as well. So, our aim in this paper is to determine an optimal stimulation mode, such as the number of required stimulated...
