![]() The ventricles beat faster too, but not as fast as the atria, and the heart beat is not as erratic as it is with fibrillation. With a flutter, the atria pump rapidly, far beyond 100 beats a minute. It’s not usually as severe a problem as AFib. Atrial flutterĪtrial flutter, like atrial fibrillation, also is caused by a short-circuit in the heart’s electrical system. Some of the most common treatments for atrial fibrillation include medication to regulate your heart rate, blood thinners to manage the risk of stroke, and medical procedures like cardioversion and ablation. Persistent and long-lasting AFib can increase the risk of stroke and other serious cardiovascular problems. You should seek medical attention if you have symptoms of atrial fibrillation that lasts longer than several days, or goes away and then returns. This type is more common in younger people, and typically doesn’t require treatment or medical intervention. If it lasts less than a week, it’s called paroxysmal atrial fibrillation. Atrial fibrillation, or AFib, can resolve itself within a few hours or a few days. This irregular heartbeat occurs in the upper chamber of the heart (the atria), so the lower chambers don’t get enough blood flow to pump efficiently.Ītrial fibrillation occurs when the heart’s electrical signals misfire and the upper chambers beat irregularly. Atrial fibrillation can make the heart race at up to 400 beats per minute, well over the normal range of 100. Some of the most common types include: Atrial fibrillationĪtrial fibrillation is the most common type of arrhythmia and affects more than two million Americans, according to the National Heart, Blood, and Lung Institute. There are several types of heart arrhythmias, based on what part of the heart they occur in and what problem they cause. ![]() If you have a history of cardiovascular problems or heart disease, you may also be at risk for more severe forms of arrhythmia.
