THE EFFECTS OF 
ATRIAL FIBRILLATION 
ON THE BODY

Afib affects the upper chambers of the heart, called the atria. It’s an electrical disorder that causes rapid electrical signals in the heart that may reach hundreds of beats per minute. The rapid-fire signals interfere with the ability of the upper chambers
to contract in an organized way.
This leads to decreased pumping action and passive blood flow. Blood can even pool within the heart. Some people with afib have no symptoms, while others experience a wide range of symptoms. Afib increases the risk of heart-related disorders and stroke.
