End Systolic Volume Calculator

End Systolic Volume Calculator calculator can be used to estimate the volume of blood in the left ventricle at the end of systole (contraction phase), which is an important indicator of cardiac function.

Calculation Formula

End Systolic Volume (ESV) = End Diastolic Volume (EDV) - Stroke Volume (SV)

Where:
ESV: End Systolic Volume - volume of blood in the left ventricle at the end of systole
EDV: End Diastolic Volume - volume of blood in the left ventricle at the end of diastole
SV: Stroke Volume - volume of blood ejected by the left ventricle with each heartbeat

Result

End Systolic Volume (ESV): -- mL

Learn how to use the End Systolic Volume Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the Stroke Volume (SV) in milliliters (mL). This is the volume of blood ejected by the left ventricle with each heartbeat.
  2. Enter the End Diastolic Volume (EDV) in milliliters (mL). This is the volume of blood in the left ventricle at the end of diastole (relaxation phase).
  3. Click the "Calculate" button to compute the End Systolic Volume (ESV).
  4. The result will be displayed in milliliters (mL).
  5. Click the "Reset" button to clear all inputs and start over.

Understanding the Results

The End Systolic Volume (ESV) represents the volume of blood remaining in the left ventricle after contraction. It's an important measure of cardiac function:

  • A normal ESV for a resting adult is typically between 50-70 mL.
  • Higher ESV values may indicate heart failure or other cardiac conditions.
  • Lower ESV values may suggest hypercontractility of the heart muscle.

Principle of Calculation

The calculator uses the following formula:

ESV = EDV - SV

This formula is derived from the basic cardiac cycle hemodynamics, where the stroke volume is the difference between the end-diastolic volume and the end-systolic volume.
