What does the formula EDV - ESV describe?

The formula EDV - ESV is used to calculate Stroke Volume, which is the volume of blood pumped by the left ventricle of the heart with each heartbeat. EDV refers to End-Diastolic Volume, representing the total volume of blood in the ventricle at the end of diastole, just before the heart contracts. ESV stands for End-Systolic Volume, which is the volume of blood remaining in the ventricle after contraction. By subtracting the ESV from the EDV, you can determine how much blood the heart is able to eject with each contraction, hence quantifying Stroke Volume.

Understanding Stroke Volume is critical in assessing cardiac function and can provide insights into various cardiovascular conditions. It is part of important calculations and concepts in critical care settings, especially for patients with compromised heart functions. Other listed choices relate to different physiological measurements or assessments and are not connected to the calculation derived from the EDV and ESV values.
