Abstract :
An experimental and theoretical approach was used to reveal and explain particular complex behavior of cardiac cells under electric field stimuli. The use of straightforward modeling forms a strong alliance with the optical recording technique to adequately explain the underlying mechanisms. Optical recordings reveal behavior that can not be explained by membrane kinetic descriptions established under physiological conditions and lead to an augmented ionic current model for the cardiac ventricular cells under investigation
