Webb3.2.3.2.2 The Simpson method to determine ejection fraction The Simpson method enables us to determine the volume of the left ventricle (see section: 3.2.2.2.2). When you perform the calculation for end-diastolic as well as end-systolic volumes, you can calculate ejection fraction by using the following formula: WebbStroke volume can be obtained by: 1) SV = EDV – ESV (when end systolic volume is known) 2) Cardiac output in mL/min / Heart rate in bpm. Example calculation from the ejection fraction calculator: for a normal range stroke volume of 70 mL and a left ventricular EDV value of 120 mL, the ejection fraction is: 70/120 = 0.58, meaning in percentage ...
