[Experimental quantitative evaluation of the cardiac pump in function].
Experimental technique has been developed that makes it possible to change left ventricular after exercise on a wide scale during one beat at an intact circulation. The relationship between the maximal blood flow rate and left ventricular systolic pressure at permanently filled ventricle and inotropic state has been shown close to linear. This relationship (exercise characteristics) can be described by two parameters: maximal systolic blood pressure at blood flow and maximal blood flow ab zero peripheral resistance, and can be used for the assessment of the cardiac pump function.
