Atrial fibrillation is an abnormal heart rhythm characterised by rapid and irregular beating.
Explanation:
Often it starts as brief periods of abnormal beating which become longer and possibly constant over a period of time.
Most episodes have no symptoms. Occasionally there may be heart palpitations, fainting , light headedness, shortness of breath or chest pain.
The disease is associated with an increased risk of heart failure, dementia and stroke.
Atrial fibrillation is often treated with medication to slow the heart rate to a normal range or to convert the rhythm to normal sinus rhythm.
