The first phase is a brief isovolumetric contraction, lasting about 0.05 s and a longer ejection phase of about 0.30 s. The isovolumetric contraction causes left ventricular pressure to rise above atrial pressure, which closes the mitral valve and produces the first heart sound.
As not all of the blood is ejected from the heart with the contraction of the ventricles, the âejection fraction is the amount that is ejected after the ventricle is filled. The main ventricle of the heart valve is the left ventricle, the ejection fraction of the heart is measured here. Therefore, it can be stated that the normal range for the left ventricle (LV) ejection fraction is 55 to 70 percent. slide 2 of 4.
