Atrial fibrillation, commonly referred to as ‘AFib’ or ‘AF’ is a heart condition where the heart rhythm is irregular and, in many cases, very fast beating above 100 beats per minute. AFib is the most common arrhythmia (abnormal heartbeat) in Ireland. It can affect people of any age but is more common in older people.[1]
If left undiagnosed or untreated, AFib increases the risk of stroke and heart failure. It has been referred to as a growing health concern.[2]
