DOMINGUEZ, Ivonne; BARRIO, Rafael A.; VAREA, Carmen  y  ARAGON, José Luis. Model for propagation of solitary waves in the heart. TIP [online]. 2013, vol.16, n.2, pp.79-92. ISSN 1405-888X.

In cardiac electrical activity, different types of waves meander through the heart. We present a model of the electrical activity of the heart that proposes that the homogeneous wave fronts propagating through the heart are in fact solitons. We use a general set of reaction-diffusion equations known as the Barrio-Varea-Aragón-Maini (BVAM) model^[1]that presents a wealth of non-linear bifurcations, and we are able to follow the route to chaos, using a mapping of the amplitude equations to the dynamics of the complex Ginzburg-Landau equation. We study the dynamics of wave fronts numerically in the BVAM model to describe the mechanisms leading to heart fibrillation and compare the findings with experimental data.

Palabras llave : Electrical activity of the heart; chaos; reaction-difusion systems; solitons.
