Atrial Flutter EKG Reference

Definition of Atrial Flutter

Atrial flutter is a very rapid pattern of atria contraction. Unlike atrial fibrillation, atrial flutter's electrical activity in the atria is coordinated. This rapid rate (250 to 350 times per minute) is too fast to allow the conduction of each impulse to the ventricles.
