What causes atrial flutter?

Atrial flutter may be caused by abnormalities of the heart, by diseases of the heart, or by diseases elsewhere in the body that affect the heart.

In a few people, no underlying cause is ever found.

Substances that may contribute to atrial flutter include the following:
