Analysis of an experimental model of in vitro cardiac tissue using phase space reconstruction
The in vitro cultures of cardiac cells are valuable models to study the arrhythmias at the cellular level. The possibility to reconstruct a mathematical model from experimental data in order to characterize it from a dynamical point of view is performed. Phase space reconstructions in normal and arrhythmic signals highlight strange attractors. The time lag, the fractal and correlation dimensions could be used for classification feature. The embedding dimension is robust against external perturbation.
