A patient has an end-diastolic volume of 125 ml. A heart attack has weakened her left ventricle so it can pump a stroke volume of only 40 ml. Calculate her end-systolic volume.
A)85 ml
B)3)1 ml
C)5000 ml
D)165 ml
E)not enough data given to calculate the end-systolic volume

Quizplus · Accepted Answer

The end-systolic volume (ESV) can be calculated using the formula: ESV = EDV - SV, where EDV is the end-diastolic volume and SV is the stroke volume. Here, ESV = 125 ml - 40 ml = 85 ml.
