using apparatus rpg2-02 to obtain the differential rheogram and postulating that at the very onset of the systolic ejection of the blood from the ventricle there are conditions approximately corresponding to the isotonic regime of cardiac performance , the authors suggest formulae to calculate the volumetric rate ( formula : see text ) volumetric acceleration ( formula : see text ) and maximum volumetric acceleration of ventricular ejection ( nmax = n x dd ) .
