Atrial Fibrillation (A-Fib)

Send an Inquiry
Atrial fibrillation (also called AF or A-Fib) is the most common type of irregular heartbeat, occurring in 1-2% of the general population. However, it is a problem that increases with age, with approximately 5-15% of people between 80-90 years of age affected. There is also an increased risk of atrial fibrillation among people with heart conditions, including irritation of the membrane surrounding the heart (pericarditis), heart muscle disease (cardiomyopathy), abnormal heart valves or congenital heart defects.
Atrial fibrillation occurs when electrical signals in the heart’s upper chambers (atrium) cause the atrium to beat quickly and erratically, causing an irregular fast heart rhythm. As a result, the heart may not be able to pump enough blood around the body or out of the atrium completely with each heartbeat. If not correctly treated, atrial fibrillation can lead to heart failure. People with atrial fibrillation also have a 5 times higher risk of a potentially fatal stroke as the condition can cause blood clotting that blocks the artery supplying blood to the brain.
