What is atrial fibrillation a symptom of?

It depends: Atrial fibrillation is an irregular rhythm in which the atria beat at nearly 400 beats/min. It is common in older patients as a reflection of aging of the conduction system. In younger patients it can be caused by alcohol and drug abuse. It can also occur when the heart dilates as in congestive heart failure. The abnormal contractions put patients at risk for blood clots which may cause strokes. ...Read more
