In many cases, doctors can identify the causes of atrial fibrillation.The electrical signal then moves down to a group of cells called the atrioventricular (AV) node, located between the atria and the ventricles.

What Is Atrial Fibrillation? - NHLBI, NIH

Atrial fibrillation (A-tre-al fi-bri-LA-shun), or AF, is the most common type of arrhythmia (ah-RITH-me-ah).It impairs cardiac function and increases the risk of stroke.

Atrial fibrillation can be caused by emotional, physical, surgical, or hormonal triggers among other influences.Atrial fibrillation can also occur in people who do not have structural heart problems.

With each heartbeat, an electrical signal spreads from the top of the heart to the bottom.The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to the body.Use the buttons in the lower right corner to pause, restart, or replay the animation, or use the scroll bar below the buttons to move through the frames.Atrial fibrillation may occur without evidence of underlying heart disease.Instead of the SA node (sinus node) directing the electrical rhythm, many different impulses rapidly fire at once, causing a very fast, chaotic rhythm in the atria.

Atrial fibrillation (AF or AFib) is the most common type of arrhythmia (irregular heartbeat).Each electrical signal begins in a group of cells called the sinus node or sinoatrial (SA) node.When the SA node fires an impulse, electrical activity spreads through the right and left atria, causing them to contract and force blood into the ventricles.Primarily a disease of aging, causes of Atrial Fibrillation may be heart, thyroid or lung disease, and is associated with high blood pressure, diabetes, sleep apnea.It causes the ventricles to contract and pump blood to the lungs and the rest of the body.
