What does EDV mean in medical terms?

EDV refers to the blood flow velocity at the end of diastole, with detailed analysis as follows:

The blood flow velocity at the end of diastole is commonly used in echocardiography and serves as an indicator for assessing cardiac function. The blood flow velocity at the end of diastole represents the speed of blood flow within the heart at the conclusion of the diastolic phase, reflecting the degree of ventricular filling. Normally, the blood flow velocity at the end of diastole should fall within a certain range; values that are too high or too low may indicate potential cardiac abnormalities. In echocardiographic examinations, the blood flow velocity at the end of diastole is typically evaluated alongside other hemodynamic parameters—such as systolic peak velocity and cardiac output—to assess both systolic and diastolic function. These combined metrics help physicians understand blood flow dynamics during cardiac contraction and relaxation, enabling detection of cardiac dysfunction and evaluation of cardiovascular disease risk. The blood flow velocity at the end of diastole also has applications in other medical fields; for example, in vascular ultrasound, it can be used to evaluate the degree of vessel stenosis and blood flow velocity, aiding in the diagnosis of vascular diseases. Additionally, the blood flow velocity at the end of diastole may be applied in the assessment of cerebral hemodynamics and other areas of neurologic interest.

If abnormal results are detected along with other symptoms, it is important to actively cooperate with medical treatment to prevent serious complications due to delayed intervention.
