Question

If the End diastolic volume in the case above is 100 and the left ventricular ejection fraction (LVEF) was 30%, what was the stroke volume?

Answer 1

The stroke volume, calculated from the End Diastolic Volume of 100 mL and an ejection fraction of 30%, is 30 mL.

Step-by-step explanation:

If the End Diastolic Volume (EDV) is 100 mL and the left ventricular ejection fraction (LVEF) is 30%, we can calculate the stroke volume (SV) using the formula for ejection fraction: SV = EDV × LVEF. In this case, we can determine the SV by simply multiplying the EDV by the LVEF percentage (expressed as a decimal).

Therefore, SV = 100 mL × 0.30 = 30 mL.

The stroke volume in this scenario would be 30 mL, which is the amount of blood ejected by the left ventricle during one heart contraction when the LVEF is 30% and the diastolic volume is 100 mL.
