BACKGROUND The effects of defibrillatory shocks on the organization of atrial fibrillation (AF) have not been studied previously. In this study, we examined the events that precede, accompany, and follow the application of atrial defibrillatory shocks. METHODS AND RESULTS We used video imaging to study the sequence of activation on the surface of the atria in the Langendorff-perfused sheep heart. We recorded transmembrane potentials simultaneously from > 20000 sites on the epicardium during… CONTINUE READING
