What is your risk of atrial fibrillation?

Atrial fibrillation (also known as AF or AFib) is the most common type of arrhythmia (irregular heartbeat or heart rhythm). The most common symptom of AF is heart palpitations (an irregular and rapid heartbeat, typically experienced as a rapid thumping in the chest). Often, the cause of AF is not known. However, some people may be more at risk of atrial fibrillation. For example, the risk of atrial fibrillation increases as we age.
