LVEDV
Also written as: LVEDV — Left Ventricular End-Diastolic Volume
Left ventricular end-diastolic volume, the amount of blood in the left ventricle at the end of diastole.
Full Definition
Left ventricular end-diastolic volume (LVEDV) represents the maximum volume of blood contained within the left ventricular cavity at the end of diastolic filling, just before systolic contraction begins. This measurement is a key parameter in assessing cardiac function and is typically obtained through echocardiography, cardiac MRI, or nuclear imaging techniques. LVEDV is used to calculate ejection fraction and stroke volume, and its normalization to body surface area helps account for patient size differences. Elevated LVEDV may indicate volume overload or heart failure.
Usage
Usage note: Always specify units (mL) and consider body surface area indexing.
