(04.01 аnd 04.02 MC) Accоrding tо the Nаtiоnаl Institute of Health, atrial fibrillation (AF) occurs if rapid, disorganized electrical signals causing the heart's two upper chambers, called the atria, to fibrillate. The term "fibrillate" means to contract very fast and irregularly. In AF, blood pools in the atria. It isn't pumped completely into the heart's two lower chambers, called the ventricles. As a result, the heart's upper and lower chambers don't work together as they should. Based on the passage above, how will atrial fibrillation affect blood pressure? (2 points)
