FitzHugh-Nagumo Simplified Cardiac Action Potential Model, 1961

The FitzHugh-Nagumo model is a simplification of the Hodgkin-Huxley (1952) model. The number of equations is reduced to two: a cubic equation representing the fast variable (u) and liniar equation for the slow variable (vv). The model was modified by Aliev and Panfilov to better approximate cardiac action potential properties.
