End-Systolic Volume Calculator

Formula

The formula to calculate the End-Systolic Volume (ESV) is:

\[ ESV = EDV - SV \]

Where:

\( ESV \) is the End-Systolic Volume (mL)
\( EDV \) is the End-Diastolic Volume (mL)
\( SV \) is the Stroke Volume (mL)

What is End-Systolic Volume?

End-Systolic Volume (ESV) is the volume of blood remaining in a ventricle of the heart after contraction (systole). It is an important parameter in cardiology, as it helps in assessing the heart's function and efficiency.

Example

Let's say the End-Diastolic Volume (EDV) is 120 mL, and the Stroke Volume (SV) is 70 mL. Using the formula:

\[ ESV = 120 - 70 = 50 \, \text{mL} \]

So, the End-Systolic Volume (ESV) is 50 mL.
