MSH: The amount of BLOOD pumped out of the HEART per beat, not to be confused with cardiac output (volume/time). It is calculated as the difference between the end-diastolic volume and the end-systolic volume.,NCI: The difference in a cardiac ventricle's blood capacity taken at times of minimum and maximum blood content. This is end diastolic volume less end systolic volume. (Dr. Joseph A. Thie)
