Incardiovascular physiology,end-diastolic volume(EDV) is the volume of blood in the right or left ventricle at end of filling indiastolewhich is amount of blood present in ventricle at the end of diastole.[1]Because greater EDVs cause greater distention of the ventricle,EDVis often used synonymously withpreload,which refers to the length of thesarcomeresincardiac muscleprior to contraction (systole). An increase in EDV increases the preload on the heart and, through theFrank-Starling mechanismof the heart, increases the amount of blood ejected from the ventricle during systole (stroke volume).[citation needed]

The right ventricular end-diastolic volume (RVEDV) ranges between 100 and 160 mL.[5]The right ventricular end-diastolic volume index (RVEDVI) is calculated by RVEDV/BSAand ranges between 60 and 100 mL/m2.[5]
