WebA normal EF ranges from 55-69%, and is calculated using the following equation: Ejection fraction (EF) in percentage is defined as: EF (%) = SV/EDV x 100. Where SV: Stroke Volume and EDV: End Diastolic Volume. Ejection fraction (EF) is basically a percentage, of how much blood the left ventricle pumps out with each contraction. WebFeb 23, 2024 · The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle (Figure 10.5. 1 ). The period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The period of relaxation that occurs as the chambers fill with blood is called diastole.
