Rapid Ventricular Filling

Ventricular pressure remains low, because the ventricle is still relaxed and compliant.

Rapid Ventricular Filling

The rapid flow of blood from the atria to the ventricles produces the third heart sound (S3).

Third heart sound (S3) 

normal in children but is not heard in normal adults

indicates volume overload, as in congestive heart failure or advanced mitral or tricuspid regurgitation.

Rapid Ventricular Filling

aortic pressure decreases as blood runs off from the aorta into the arterial tree, to the veins, and then back to the heart.
