What is the normal value of EF in left ventricle of heart?

The normal value of EF of left ventricle is about 50%-75%.

EF is the ejection fraction, which is measured only in the left ventricle. It refers to the percentage of blood volume pumped by the heart at one beat to the end-diastolic volume of the ventricle. It can be used to reflect the pumping function of the heart. The normal left ventricular ejection fraction should be about 50%-75%. If the examination result exceeds 75%, it is considered to be high, but it has no clinical significance. If
