Overview
Atrial fibrillation (AF or afib) is a cardiac arrhythmia (abnormal heart rhythm) that involves the two upper chambers (atria) of the heart. Atrial fibrillation is an irregularly irregular heart beat due to chaotic firing of the impulses in the atrium. In this rhythm, the atrium is stimulated chaotically by a wide number of ectopic foci of electrical activity.
Classification
Although several clinical classification plans and protocols have been proposed, none of them fully account for all aspects of atrial fibrillation. The American Heart Association, American College of Cardiology, and the European Society of Cardiology have proposed a classification system based on simplicity and clinical relevance.[1] This classification system contains four main categories which are: first detected or diagnosed, paroxysmal, persistent, and permanent atrial fibrillation.
