- In a patient with a ventricular septal defect, blood is ejected from the left ventricle into the right ventricle during isovolumic contraction phase of the cardiac cycle.

The amount of blood found within the left ventricle just after ejection and before the left AV valves opens is called the _____________________ (EDV, ESV, EF). Clinically, one of the best parameters used to measure cardiac function is the EF. In terms of EDV and ESV, what simple equation would give you the EF? If you had an echocardiogram and found that your EDV was 100 cc and your ESV was 30 cc, what would be your EF? EDV = end-diastolic volume, ESV = end-systolic volume, EF = ejection fractionarrow_forward
