Atrial fibrillation and atrial flutter are very fast electrical discharge patterns that make the atria contract very rapidly, with some of the electrical impulses reaching the ventricles and causing them to contract irregularly, faster, and less efficiently than normal.
Although atrial fibrillation and atrial flutter are both fast heart rhythms, they are not the same thing. In this video, Ronald Walsh, DO, of Largo Medical Center, explains how the treatments for atrial fibrillation and atrial flutter differ.
