atrial fibrillation
Also known as A-fib, AF, AFib
abnormal heart rhythm characterized by rapid and irregular beating
AI overview
Atrial fibrillation is a condition where the upper chambers of your heart beat rapidly and irregularly instead of in a steady, coordinated rhythm. It matters because this abnormal beating can reduce how efficiently your heart pumps blood and may lead to serious complications.

Article
Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. It often begins as short periods of abnormal beating, which become longer or continuous over time. It may also start as other forms of arrhythmia, such as atrial flutter, that transform into AF.
Episodes can be asymptomatic. Symptomatic episodes may involve heart palpitations, fainting, lightheadedness, loss of consciousness, or shortness of breath. Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. It is a type of supraventricular tachycardia.
