Atrial fibrillationAn abnormal and irregular heart rhythm in which electrical signals are generated chaotically throughout the upper chambers (atria) of the heart. Many people with atrial fibrillation have no symptoms. Among those who do, the most common symptom is an uncomfortable awareness of the rapid and irregular heartbeat (palpitations). Atrial fibrillation can [..]

Atrial fibrillationA type of arrhythmia in which your atria beat extremely fast, up to 400 times per minute and your ventricles respond by beating quickly and irregularly. This can lead to a clot forming inside your hea [..]

Atrial fibrillationA disorder of heart rhythm in which the normally regular contractions of the atria of the heart are replaced by rapid and random twitching, resulting in irregular and usually faster than usual contrac [..]

Atrial fibrillationA disorder in which the two upper chambers of the heart beat fast and erratically. Because blood isn't pumped out of these chambers fully, it may pool and form clots that could lead to a stroke.

Atrial fibrillationa cardiac arrhythmia, characterized by rapid, uncoordinated beating of the atria, which results in ineffective atrial contractions. Atrial fibrillation is known as a supraventricular arrhythmia becaus [..]

Atrial fibrillationA heart condition that causes an irregular and often abnormally fast heart rate (1). AF is more likely to occur in people with other conditions such as high blood pressure or atherosclerosis. Although it can affect adults of any age it affects more men than women and becomes more common with old age. About 1 in 200 people aged 50-60 have AF. This r [..]
