Atrial Fibrillation, or AFib/AF for short, is the most common heart rhythm disorder in the world and is estimated to affect 1 million people in the UK.
The heart has four chambers, and the top two are known as the atria (see figure below). Contraction of the heart is controlled by an electrical system with a pacemaker located at the top of the right atrium. As people age, and when other conditions such as high blood pressure develop, the ability to conduct electricity in the atria changes and can become chaotic, called fibrillation. When the atria fibrillate, the atria do not contract at all and blood inside can stagnate and form clots. Clots from the heart can break off and make their way to the brain resulting in a stroke. This is why AFib is the leading cardiac cause of stroke in young people.
