Atrial fibrillation induced by interference of regular wave fronts with fronts emanating from a spiral wave — •Claudia Hamann, Mario Einax, and Philipp Maass — Institut für Physik, Technische Universität Ilmenau, Germany

We investigate the interference of a stable spiral wave in the left atrium with regular paced waves in the right atrium as generating mechanism of atrial fibrillation on the basis of the FitzHugh-Nagumo model. We show that this interference scenario is a possible cause of fibrillation in the right atrium. A high pacing rate can yield an irregular, fibrillatory state and is seen as a key factor for the occurrence of fibrillation episodes [1].
