AtrialFibrillation(A-Fib) or (AF) 


A cardiac arrhythmia characterized by disorganized electrical activity in the atria accompanied by an irregular ventricular response that is usually rapid. The atria quiver instead of pumping in an organized fashion, resulting in compromised ventricular filling and reduced stroke volume. Stasis of left atrial flow increases the risk of stroke as a result of clot formation. AF is associated with hypertension,

diabetes, age, rheumatic heart disease (left atrial dilation), mitral stenosis, acute myocardial infarction, and heart surgery, or it may be idiopathic (lone AF). Treatment goals are to control the ventricular rate by creating atrioventricular block, to prevent stroke through the use of anticoagulants, and to convert to sinus rhythm. Treatment categories include paroxysmal, persistent, and chronic. AF is called controlled if ventricular response is less than 100. If ventricular response is 100 or more, it is called uncontrolled atrial fibrillation.
