One-dimensional representaion of myocardium and approximation of the cell membrane by resistor-capacitor circuit. The circuit consists of a nonlinear resistor dependent on the ionic concentrations (sodium [Na]⁺, potassium [K]⁺ and leakage currents) of intra- and extracellular domains and a capacitor .
