Cardiac output (CO) as a mean blood flow from heart ventricle is heart rate (HR) multiplied by stroke volume (SV), where stroke volume is difference of end diastolic volume (EDV) [Gaasch1975,Carter1998] and end systolic volume (ESV) [Noda1993]. The HR and heart contractility (in the meaning of ESV) [Suga1976] can be influenced by nervus vagus (main parasympathicus autonomic neural pathway) [Xenopoulos1994], epinephrine [Collins-Nakai1994] or angiotensin II [Kumagai1994]. The most comon descriptions are pressure-volume relations [Sawaga1988] as in famous A-V fistula experiments [Guyton1961] or filling pressure experiments [Suga1974] or less invasive exercise experiments [Little1993].
There is some evidence of non-steady state behaviour of end diastolic volume, because the stroke volume is dependent on heart rate [Ross1965,Sugimoto1966].
