What is end-systolic volume (ESV)?

End-systolic volume is the amount of blood left in the ventricle after the heart has finished contracting (after systole). It represents the residual volume once ejection is complete and is used with end-diastolic volume to calculate stroke volume (SV = EDV − ESV). The volume described as occurring at the end of diastole corresponds to end-diastolic volume, which is the maximum ventricular filling right before contraction, not the amount remaining after contraction. So end-systolic volume is best understood as the volume remaining after systole, not the volume at the end of diastole.
