How Does Atrial Fibrillation Cause Stroke?

Atrial fibrillation patients are more likely to have strokes than people with normal heart rhymes. Their heart pumps irregularly. When a person has atrial fibrillation, the upper chambers of the heart (atria) beat up to four times faster than the rest of the heart. Due to the ineffective contractions of the upper chambers, the blood can’t eject as it is supposed to, therefore, it pools and stagnates in the atria.

As blood flows sluggishly, it gradually becomes thicker and thicker. Finally, blood clots are formed in the atria, especially in the left atrium. Any one of the blood clots can dislodge from the appendage and travel to other parts of the body. When it comes to the brain and cuts off oxygen supply to a portion of the brain, a stroke occurs suddenly.
