Cardiac input (CI) is the inverse operation of cardiac output. As cardiac output implies ejection fraction, cardiac input implies injection fraction (IF).
IF = end diastolic volume (EDV) / end systolic volume (ESV)
Cardiac input is a readily imaged mathematical model of diastole.

Famous quotes containing the word input:
“Celebrity is a mask that eats into the face. As soon as one is aware of being “somebody,” to be watched and listened to with extra interest, input ceases, and the performer goes blind and deaf in his overanimation. One can either see or be seen.”
—John Updike (b. 1932)
