Atrial flutter symptoms can come and go, with fast heart beat episodes lasting from some hours or days. In some cases, atrial flutter happens all the time. With proper treatment, atrial flutter is rarely life threatening. Complications of atrial flutter can be serious, but they can usually be prevented with treatment.
Atrial flutter is an abnormality in the beating of the heart. Such abnormalities, whether in the rhythm or speed of the heartbeat, are known as arrhythmias. The heart is a muscle that pumps the blood through the body. 1  Each beat of the heart is a very rapid series of two contractions.
