Atrial Fibrillation: A Historical Perspective

Atrial fibrillation (AF) has undoubtedly become one of the most well-studied arrhythmias today in terms of pathophysiology and diagnostic and therapeutic (interventional) electrophysiology. Although it lends itself to an apparently easy diagnosis on the surface electrocardiography, myriad electromechanical mechanisms underlie its origin. We have now reached an era of technology that makes AF not only “treatable” but potentially “curable.” This article aims at walking through the historical “corridors” and “mazes” that led to the present day understanding of this common yet complex arrhythmia.
