Pressure-volume loops comparing a control state (solid line) and the addition of a positive inotropic agent (dotted line), assuming constant stroke volume. Beginning with A, end-diastole, the period from A to B represents isovolumetric left ventricular contraction. Ejection occurs from B, opening of the aortic valve to C, end-systole. The period from C to D, opening of the mitral valve, represents isovolumetric relaxation, and is followed by ventricular filling in the period from D to A.
