end-diastolic volume
(redirected from End diastolic volume)

   Also found in: Wikipedia 0.01 sec.
volume /vol·ume/ (vol´ūm) the measure of the quantity or capacity of a substance. Symbol V or V.
end-diastolic volume  (EDV) the volume of blood in each ventricle at the end of diastole, usually about 120–130 mL but sometimes reaching 200–250 mL in the normal heart.
end-systolic volume  (ESV) the volume of blood remaining in each ventricle at the end of systole, usually about 50–60 mL but sometimes as little as10–30 mL in the normal heart.
expiratory reserve volume  the maximal amount of gas that can be exhaled from the resting end-expiratory level. Abbreviated ERV.
forced expiratory volume  the fraction of the forced vital capacity that is exhaled in a specific number of seconds. Abbreviated FEV with a subscript indicating how many seconds the measurement lasted.
inspiratory reserve volume  the maximal amount of gas that can be inhaled from the end-inspiratory position.
mean corpuscular volume  the average volume of erythrocytes, conventionally expressed in cubic micrometers or femtoliters per red cell.
minute volume  (MV) the quantity of gas exhaled from the lungs per minute; tidal volume multiplied by respiratory rate.
packed-cell volume  (PCV), volume of packed red cells (VPRC) hematocrit.
residual volume  the amount of gas remaining in the lung at the end of a maximal exhalation.
stroke volume  the volume of blood ejected from a ventricle at each beat of the heart, equal to the difference between the end-diastolic volume and the end-systolic volume.
tidal volume  the volume of gas inhaled and exhaled during one respiratory cycle.

end-diastolic volume
n.
The amount of blood in the ventricle immediately before a cardiac contraction begins; used as a measurement of diastolic function.

First, the increase in end diastolic volume that comes with age, means there is more blood to pump; and second, the greater volume stretches the ventricular walls and brings into play a peculiar property of muscle cells--the more they are stretched, the more they contract.
Cardiac cycle parameters, such as Heart Rate, End Systolic Pressure, End Diastolic Pressure, Max Pressure, Min Pressure, Max dP/dt, Min dP/dt, Max Volume, Min Volume, End Systolic Volume, End Diastolic Volume, Stroke Volume, Cardiac Output, Ejection Fraction, and Stroke Work can be monitored online.
