Calculate End-Systolic Volume (ESV)



Formula

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

\[ ESV = EDV - SV \]

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.

End-Systolic Volume

Definition: End-systolic volume (ESV) is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole.

Formula: \( ESV = EDV - SV \)

Example: \( ESV = 120 - 70 \)

End-Systolic Volume Index

Definition: End-systolic volume index (ESVI) is the end-systolic volume normalized to body surface area.

Formula: \( ESVI = \frac{ESV}{BSA} \)

Example: \( ESVI = \frac{50}{1.8} \)

End-Diastolic Volume Calculation

Definition: End-diastolic volume (EDV) is the volume of blood in the ventricle at the end of filling, or diastole.

Formula: \( EDV = ESV + SV \)

Example: \( EDV = 50 + 70 \)

Calculate End-Diastolic Volume

Definition: This calculation determines the end-diastolic volume based on stroke volume and end-systolic volume.

Formula: \( EDV = SV + ESV \)

Example: \( EDV = 80 + 60 \)
