What is atrial fibrillation?
So atrial fibrillation is a difficult Greek word that doesn’t mean anything to the layperson. But it’s actually the commonest rhythm disturbance of the heart. So a normal heartbeat is regular, about one beat per second. In atrial fibrillation, the heartbeat becomes irregular like that. And that is associated with risks of breathlessness, palpitations, and if it’s not managed appropriately, it can even cause a stroke.
