Some people with occasional A-fib need treatment. Sometimes symptoms occur for as long as a week and episodes can happen repeatedly. A-fib symptoms come and go, usually lasting for a few minutes to hours. Occasional (paroxysmal atrial fibrillation).Sensations of a fast, fluttering or pounding heartbeat (palpitations).Those who do have atrial fibrillation symptoms may have signs and symptoms such as: Some people with atrial fibrillation (A-fib) don't notice any symptoms. However, A-fib may cause a fast, pounding heartbeat (palpitations), shortness of breath or weakness. For many people, A-fib may have no symptoms. A-fib increases the risk of stroke, heart failure and other heart-related complications.ĭuring atrial fibrillation, the heart's upper chambers (the atria) beat chaotically and irregularly - out of sync with the lower chambers (the ventricles) of the heart. Since the atrioventricular (AV) node doesn't prevent all of these chaotic signals from entering the ventricles, the heart beats faster and irregularly.Ītrial fibrillation (A-fib) is an irregular and often very rapid heart rhythm (arrhythmia) that can lead to blood clots in the heart. In atrial fibrillation, electrical signals fire from multiple locations in the atria (typically pulmonary veins), causing them to beat chaotically. The signal then travels through the atria to the atrioventricular (AV) node and passes into the ventricles, causing them to contract and pump out blood. In a typical heart, a tiny cluster of cells at the sinus node sends out an electrical signal.
