Cardiac input
Cardiac input is the inverse operation of cardiac output
Cardiac output
Cardiac output is the volume of blood being pumped by the heart, in particular by a left or right ventricle in the time interval of one minute. CO may be measured in many ways, for example dm3/min...


Cardiac output implies ejection fraction
Ejection fraction
In cardiovascular physiology, ejection fraction is the fraction of Blood pumped out of the Right Ventricle of the heart to the Pulmonary Circulation and Left Ventricle of the heart to the Systemic Circulation with each Heart beat or Cardiac cycle...


Ejection fraction is an easily understood and inexpensively imaged mathematical model of systole
Systole (medicine)
Systole is the contraction of the heart. Used alone, it usually means the contraction of the left ventricle.In all mammals, the heart has 4 chambers. The left and right ventricles pump together. The atria and ventricles pump in sequence...


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
Injection fraction
Injection fraction, or end diastolic volume divided by end systolic volume of the ventricles or IF=EDV/ESV, is the inverse mathematical operation of the Myocardium derived Ejection Fraction. "Ejection Fraction" is historically and mathematically derived from Cardiac Output first posited by Adolph...


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

Cardiac input is a readily imaged mathematical model of diastole
Diastole is the period of time when the heart fills with blood after systole . Ventricular diastole is the period during which the ventricles are relaxing, while atrial diastole is the period during which the atria are relaxing...
