| == Atrial fibrillation (AF or afib) is a [https://www.wikidoc.org/index.php/Cardiac_arrhythmia cardiac arrhythmia] (abnormal heart rhythm) that involves the two upper chambers ([https://www.wikidoc.org/index.php/Atrium_(anatomy) atria]) of the [https://www.wikidoc.org/index.php/Heart 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. ==
