Atrial flutter is a very rapid, regular heartbeat that starts in the atria, or upper chambers of the heart.
What is going on in the body?

Only some of the beats get through, so the entire heart doesn't usually beat as fast as the atria.
What are the causes and risks of the condition?
Atrial flutter is caused by a short circuit in one atrium. The electrical system starts running out of control, forcing the heart to beat rapidly. Factors linked to atrial flutter include:
