In this paper we present a method for generating a simulated atrial fibrillation (AF) signal using the superimposed output of two ECGSYN engines. This method is based on an atrial fibrillation model proposed by Zeng and Glass [8] in which a number of atrial waves conduct and cause ventricular activation. To create a synthetic AF signal we first generated a series . . . . . . realistic dynamical model of the electrocardiogram.
