Atrial fibrillation, often referred to as “A-fib,” is an electrical disorder in the heart’s upper chambers that causes an abnormal heart rhythm (arrhythmia) and disrupts the normal flow of blood between the upper and lower chambers. Left untreated, A-fib can lead to serious complications, including blood clots, stroke, and heart failure.

A-fib is the most common irregular heart rhythm, leading to 450,000 hospitalizations each year. Recent studies estimate that it affects approximately 10 million people in the United States—about 5 percent of the population—and that number is expected to exceed 12 million by 2030.
