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 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.
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.
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 is the most common serious abnormal heart rhythm and, as of 2020, affects more than 33 million people worldwide. [ 3][ 22] As of 2014, it affected about 2 to 3% of the population of Europe and North America. [ 4] This was an increase from 0.4 to 1% of the population around 2005. [ 28]
Atrial fibrillation is a heart condition that causes an irregular and often abnormally fast heart rate. A normal heart rate should be regular and between 60 and 100 beats a minute when you're resting. You can measure your heart rate by checking your pulse in your wrist or neck.
Atrial fibrillation is a type of abnormal heartbeat. It is sometimes known as Afib or AF. Having atrial fibrillation can increase your risk of stroke. There are several treatments for atrial fibrillation, including medicines or a pacemaker.
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.
Atrial fibrillation (AF) reduces your heart’s ability to pump blood and this lack of flow inside the atrium can lead to a blood clot. If this clot breaks away and travels to the brain, it can result in a stroke. AF can trigger a rapid heart rate. This may reduce the filling of the ventricle and lead to heart failure.
