What is atrial fibrillation?
Atrial fibrillation is the most common type of irregular heartbeat. Atrial fibrillation causes the heart to work inefficiently so it can reduce the person’s ability to exercise and may lead to heart failure. Atrial fibrillation makes the blood flow inside the heart somewhat irregular, which can cause blood clots to form there. Consequently, atrial fibrillation carries a risk of stroke.
It is estimated more than 500,000 people in Australia suffer from atrial fibrillation. The incidence and prevalence of atrial fibrillation is rising, largely due to the epidemic of ‘diabesity’. It is likely that the size of the problem has been underestimated because one type of atrial fibrillation, paroxysmal atrial fibrillation, is difficult to identify. If you would like more information about atrial fibrillation, you can find out more from our special report, Change of Heart: time to end cardiovascular complacency.
