This example solves the modified FitzHugh-Nagumo activation model by Aliev and Panfilov (1996), defined by a CellML version of the model.
Their modifications to the original FHN model are designed to allow the model to better represent the action potential shape and restitution properties of cardiac tissue. The image below illustrates the restitution properties of the model, with the yellow trace the free action potential, the green for a cycle length of 700ms, and the red for a cycle length of 350ms.
NOTE: This example requires a CellML 1.0 enabled version of CMISS to run.
