Atrial Fibrillation

Atrial fibrillation is a common heart disorder. The heart has four chambers which work together to move blood through the body. In atrial fibrillation, there are rapid, irregular beats that are out of rhythm. These rapid beats make it hard for the chambers to empty blood completely so blood can thicken, which increases the chance of clots. These clots can travel to the brain and cause a stroke. Coumadin® (warfarin) lowers the chance of the clots forming.
