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.
What is atrial fibrillation? atrial fibrillation is a very common condition that makes the heart beat irregularly unlike the normal heartbeat that is regular. The top chambers of the heart âthe atriaâ quiver in a very rapid and chaotic pattern so blood flow slows down or stagnates.
