Atrial fibrillation directory
Atrial fibrillation, also called AF, is the most common type of irregular heartbeat, affecting up to 800,000 people in the UK. Atrial fibrillation happens when the heartbeat signal does not travel properly through the upper chambers of the heart, or atria. Atrial fibrillation might feel like heart palpitations, chest pain or shortness of breath, or it may not have any symptoms at all.
