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 more likely to occur in people who have some form of heart disease or medical condition such as congestive heart failure, rheumatic valve disease, congenital heart disease, lung disease such as emphysema, or high blood pressure. It can also occur in people with no prior heart problems.
