End Systolic Volume Calculator

End Systolic Volume Calculator calculator can be used to calculate the volume of blood remaining in the left ventricle after contraction, 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 (ml) - volume of blood remaining in the left ventricle after contraction
EDV = End Diastolic Volume (ml) - volume of blood in the left ventricle at the end of diastole
SV = Stroke Volume (ml) - volume of blood ejected by the left ventricle with each heartbeat

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 (when the heart is relaxed and filled).
  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 fields and start over.

Understanding the Results

The End Systolic Volume (ESV) represents the volume of blood remaining in the left ventricle after contraction. This value is an important indicator of cardiac function:

  • Normal ESV: Typically ranges from 50-70 ml
  • High ESV: May indicate heart failure or hypertrophy
  • Low ESV: May indicate improved cardiac function

Principle of Calculation

The calculator uses the following formula to calculate ESV:

ESV = EDV - SV

This formula is derived from the basic cardiac equation that relates the volume of blood in the ventricle at different phases of the cardiac cycle.
