can you tell me how is the magnitude of the isovolumetric relaxation altered by the increase of the ventricular lusitropy?

Increased: Isovolumetric relaxation is one of the most miraculous properties of the heart that needs to "actively relax" by untwisting in order to accommodate incoming blood in diastole, the relaxation phase of the cardiac cycle that produces the lower blood pressure number. Lusitropy is a term describing capacity for diastolic relaxation and isovolumetric relaxation increases with increases in lusitropy.
