<unk>  is a medical imaging test used to determine a person's heart function in the right, or left ventricle.<unk>  involves injecting contrast media into the heart's ventricle(s) to measure the volume of blood pumped.<unk>  can be performed with a radionuclide in radionuclide<unk>  or with an iodine-based contrast in<unk>  chamber catheterization. The 3 major measurements obtained by<unk>  are: # Ejection Fraction # Stroke Volume #<unk>  Output These three measurements share a commonality of ratios between end systolic volume and end diastolic volume and all lend mathematical structure to the common medical term systole.
