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.
In atrial flutter, your heart's upper chambers (atria) beat too quickly. This causes the heart to beat in a fast, regular rhythm. Atrial flutter is a type of heart rhythm disorder (arrhythmia) caused by problems in your heart's electrical system.
