Cardiac input (CI) is the inverse operation of cardiac output (CO).

Cardiac output implies ejection fraction.

Ejection fraction is an easily understood and imaged mathematical model of systole.

Ejection fraction (EF) = end systolic volume (ESV) divided by end diastolic volume (EDV).

Cardiac output is a mathematical model of systole.

Cardiac input implies injection fraction (IF).

IF = end diastolic volume (EDV) divided by end systolic volume (ESV).

Cardiac input is a readily imaged mathematical model of diastole.
