What is atrial fibrillation (AFib)?

AFib is the most common type of heartbeat disorder where the heart rate and heart rhythm are irregular. AFib can cause the heart to pump very fast and unevenly. If blood doesn’t move properly in the heart it can lead to the formation of blood clots. These clots can travel to the brain, and block the flow of blood. When blood doesn’t get to the brain, you can experience a stroke. AFib affects approximately 350,000 people in Canada and is the most common heart rhythm abnormality for adults.
