![]() ![]() Chronic Atrial FibrillationĪtrial Fibrillation may be referred to as acute or chronic. Persistent Atrial Fibrillation refers to the permanent state of atrial fibrillation. Paroxysmal Atrial Fibrillation usually lasts hours or days. Paroxysmal refers to the frequency with which one experiences atrial fibrillation. While in atrial fibrillation the atria quiver irregularly. So the flutter is fast and regular (maybe 250-350 beats per minute). The beats of an atrial flutter are coordinated and the beats of an atrial fibrillation are uncoordinated. This clot then can be pushed through the heart and become lodged in an artery in the brain causing a stroke.Ītrial fibrillation is also referred to as “A-Fib” or “AF.” ![]() The biggest risk factor with atrial fibrillation is that the blood, while trapped in the atria will coagulate, or form a clot. In atrial fibrillation, the beat is irregular. Instead they ‘quiver’ and blood is not pushed down into the ventricles as it should be. In atrial fibrillation, the atria do not contract normally. Definition: What is Atrial Fibrillation & Flutter?Ītrial fibrillation is an abnormal heart rhythm. The second part, or the ‘dub’ beat, is the contraction of the atria and ventricles contract (blood is pushed into ventricles from atria and pushed out of heart by ventricles). The first is usually a little softer and the second is has more emphasis.ĭuring this first beat, or the ‘lub’ beat, the atria and ventricles are relaxed and are filling with blood. What we normally refer to as one heart beat, can actually be divided into two beats. The left ventricle fills and expels this oxygenated blood out to the whole body through the aorta.From the lungs it returns to the heart entering the left atrium, once the atrium is full of this oxygenated blood, it flows down into the left ventricle.The right ventricle fills and expels this blood out to the lungs where it is oxygenated. ![]()
