Atrial fibrillation (AF) is an abnormal heart rhythm (arrhythmia) characterised by rapid and irregular beating. This is caused by unusual electrical activity in the upper chambers (atria) of the heart which causes the lower chambers (ventricles) to beat quickly and irregularly.
Mar 8, 2024 · During atrial fibrillation, the heart's upper chambers — called the atria — beat chaotically and irregularly. They beat out of sync with the lower heart chambers, called the ventricles. For many people, AFib may have no symptoms. But AFib may cause a fast, pounding heartbeat, shortness of breath or light-headedness.
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. [11] [12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4]
Atrial fibrillation (AF or Afib) is a type of arrhythmia in which your heart beats irregularly and often fast. This reduces your heart’s ability to pump blood properly and increases the chance of a blood clot forming in your heart and travelling up to your brain, where it can cause a stroke.
Mar 27, 2023 · Atrial fibrillation, also called AFib or AF, is the most common type of irregular heartbeat. The abnormal firing of electrical impulses causes the atria (the top chambers in the heart) to quiver (or fibrillate). View an animation of AFib.
Mar 24, 2023 · Atrial fibrillation, also called AFib or AF, can feel weird and frightening. But an “attack of AFib” usually doesn’t have harmful consequences by itself. The real danger is the increased risk for stroke.
Mar 23, 2023 · Atrial fibrillation is a quivering or irregular heartbeat, or arrhythmia. Atrial fibrillation, also known as AFib or AF, can lead to blood clots, stroke, heart failure and other heart-related complications. Over 12 million people are projected to have AFib by 2030.
Atrial fibrillation - or AF - is a common abnormal heart rhythm. This short illustrated leaflet explains what it is, what the symptoms are and how you can treat it. It's useful for you if you've been diagnosed with AF or if you think you might have the symptoms of it.
Nov 30, 2022 · Atrial fibrillation, also known as A-fib or AF, is one of the most common types of arrhythmias (irregular heart rhythms). Atrial fibrillation causes your heart to beat irregularly and sometimes much faster than normal, and your heart’s upper and lower chambers do not work together as they should.
May 1, 2022 · Atrial fibrillation (also called Afib or AF) is an irregular heart rhythm that begins in the upper (atria) of your heart. If you have atrial fibrillation, the normal cycle of electrical impulses in your heart is interrupted.
