A. Left ventricular pressure–volume (P–V) loop, the segments of which correspond to events of the cardiac cycle: diastolic ventricular filling along the
passive P–V curve (phase I), isovolumetric contraction (phase II), ventricular ejection (phase III), and isovolumetric relaxation (phase IV). B. The ventricle
ejects to an end-systolic volume determined by the peak isovolumetric P–V line; an isovolumetric contraction (large arrowheads) from varying end-diastolic
volumes (preload). Reproduced with permission from Sperelakis N, Banks RO: Essentials of Physiology. 2nd ed. Boston: Little, Brown and Company;
