Everything You Need To Know About Atrial Fibrillation

Atrial fibrillation is an irregular, sometimes rapid heart rate that increases an individual's risk of heart-related complications including stroke and heart failure. The atria, the heart's upper chambers, beat out of sync with the ventricles, the lower chambers of the heart. Atrial fibrillation is the most common condition of irregular heart rhythm and exists in at least one percent of the population. The condition becomes more common as age increases. It is rare in young people and more common in individuals over eighty years old.
