A. there is not enough time between beats for the left ventricle to fill with blood.
B. blood from the atria fills the ventricles too quickly due to the rapid heart rate.
C. tachycardia causes widespread vasodilation, which lowers the blood pressure.
D. afterload increases, which causes the ventricles to work against higher pressure.
