Webwhere SV is stroke volume (in L), EDV is end-diastolic volume (in L), and ESV is end-systolic volume (in L). Thus SV can be changed only by alterations in EDV and/or ESV. An increase in ventricular filling (preload) will result in an increase in the EDV and a larger SV. Doctors use left ventricular end-diastolic volume to estimate cardiac preload, which is how much the cardiac fibers of the ventricle stretch before contraction. Doctors are unable to test preload directly, so they use end-diastolic volume as a close estimate. See more Doctors use both end-diastolic volume and end-systolic volume to calculate strokevolume. End-systolic volume is the amount of blood … See more Ejection fraction refers to the proportion of blood that leaves the left ventricle during systole relative to the end-diastolic volume.
