Mathematical Modeling of Atrial Fibrillation

Electrical activity of the heart during ventricular fibrillation was modeled as a sum of N independent pulse streams with various amplitude-frequency and phase characteristics. The data of computational experiments were compared with the results of actual physiological experiments on dogs. Identification of the model was performed using the least square method. The proposed technique provides the computer simulation for studies of the internal structure of irregularities of atrial fibrillation.
