Abstract: Our aim was to find a simple method of diagnosing the different stages of atrial fibrillation. Using only the time dependence of the action potential of a myocardial cell, an appropriate modified FitzHugh-Nagumo (MFHN) approximation to the electrical function is obtained. A criterion which successfully discerns between healthy patients and patients with different stages of atrial fibrillation (AF) is derived. This method can be used effectively to diagnose AF.

Keywords: modified FitzHugh-Nagumo; MFHN; approximate action potential; atrial fibrillation diagnosis; myocardial cells; electrical response; heart cells.
