Ejection fraction, stroke volume and cardiac output lend mathematical structure to the common medical term 'systole'. Which of the following techniques yields these crucial measurements for diagnosis of cardiovascular function?

Cardiac ventriculography yields three crucial measurements for diagnosis of cardiovascular function. They are ejection fraction, stroke volume and cardiac output. They all lend mathematical structure to the common medical term 'systole'. Cardiac ventriculography involves injecting contrast media into the heart's ventricle(s) to measure the volume of blood pumped.
