As a medical professional with expertise in cardiology, I can provide you with information on the ejection fraction, which is a key measurement used to assess the heart's pumping ability.

The ejection fraction (EF) is expressed as a percentage and indicates the proportion of blood pumped out of the heart with each beat. It is calculated using the following formula:

**Ejection Fraction (EF) = (Stroke Volume / End-Diastolic Volume) × 100**

Ejection fraction is most commonly measured using echocardiography. This non-invasive technique provides good estimates of end-diastolic (EDV) and end-systolic volumes (ESV), and stroke volume (SV = EDV-ESV). Normally, EF is >60%. For example, if the SV is 75 ml and the EDV is 120 ml, then the EF is 63%.
