What is the typical value of End-Diastolic Volume (EDV)?

The typical value for End-Diastolic Volume (EDV) is around 120 ml, which represents the volume of blood in the ventricles at the end of diastole, just before the heart contracts. This metric is crucial for understanding cardiac function because it reflects the capacity of the ventricles to hold blood. A volume of 120 ml is considered a healthy approximation for an average adult's heart, indicating that the heart fills sufficiently during the relaxation phase.

Variations in this volume can be influenced by several factors, including body size, gender, and physical condition. For example, trained athletes may have a slightly higher EDV due to increased heart efficiency and volume. Understanding the typical value allows clinicians and researchers to assess potential abnormalities in cardiac health and function, such as in cases of heart failure where EDV may be elevated.

The other values presented, such as 50 ml, 100 ml, or 140 ml, do not accurately reflect the average EDV for a healthy adult heart and may indicate pathological conditions or variations outside the norm. This context is vital for interpreting cardiac health assessments.
