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 a rapid regular atrial rhythm due to an atrial macroreentrant circuit. Symptoms include palpitations and sometimes weakness, effort intolerance, dyspnea, and presyncope. Atrial thrombi may form and embolize. Diagnosis is by ECG.
