Atrial fibrillation (AF or AFib) is the most common irregular heart rhythm in the United States. Atrial fibrillation is an abnormal heart rhythm originating in the atria (top chambers of the heart). Instead of the impulse traveling in an orderly fashion through the heart, many impulses begin simultaneously and spread through the atria, causing a rapid and disorganized heartbeat.
At one time, atrial fibrillation was thought to be a harmless annoyance. However, atrial fibrillation is now recognized as a dangerous condition. Atrial fibrillation doubles the risk of death. It also increases the risk of stroke five to seven times compared to a person without atrial fibrillation. In addition, atrial fibrillation may cause congestive heart failure and uncomfortable symptoms related to a rapid heart rate. Learn more about atrial fibrillation (afib).
