Quizplus · Accepted Answer

In atrial fibrillation the atria do not contract normally; they quiver.This increases the chance of the blood clotting in the atria because of a lack of complete emptying of the atria.These clots can break free and cause embolic strokes and pulmonary emboli.Atrial fibrillation does not indicate impending myocardial infarction or an increased risk of deep venous thrombosis.Atrial fibrillation decreases cardiac output from the loss of atrial kick.
