The French sometimes refer to atrial fibrillation (AF) as l'arythmie complète, which literally means the complete arrhythmia. The actual sense in French is that AF results in complete irregularity of cardiac rhythm. However, AF can also be considered the complete arrhythmia in the sense of the consummate nature of its mechanisms and determinants. There is evidence for involvement of all forms of arrhythmia mechanisms in AF, including enhanced automaticity, delayed afterdepolarizations, early afterdepolarizations and reentry. A rich and wide range of determinants have been found to be involved in the pathophysiology of AF—various forms of ionic remodeling, structural remodeling, changes in connexin function and distribution, a whole gamut of signaling systems, anatomical determinants related to the complex three-dimensional atrial structure, hemodynamic factors and the involvement of electrical activity in the great veins. Research on the mechanisms of AF, and related therapeutic developments, has exploded over the past 10 years, and
