Atrial Fibrillation & Atrial Flutter

Aug 20th 2008

Atrial fibrillation is one of the most common arrhythmias (abnormal heart rhythm) of the heart and the most common “sustained” arrhythmia, meaning that it does not go away without treatment.  Atrial fibrillation affects more than 2 million Americans but is common worldwide.  It can affect individuals of any age although it is more common in older individuals.  It is also more common in those with other heart disease or heart disease risk factors.
