The atrial myocardium of patients with chronic atrial fibrillation (AF) is often abnormal in its histologic features and in its electrophysiologic properties. These abnormalities have been interpreted in some cases as the cause of AF and in others as a consequence of AF. We believe that both are the case. We will review the features of this atrial myopathy and discuss the likely mechanisms and consequences of the process.
