U01.21.022 Stroke Volume (SV)

Written by

Learning Objective:
Understand and apply the formula for stroke volume (SV), which measures the volume of blood ejected by the heart with each beat.

Formula:

$SV = EDV - ESV$

Explanation:

$EDV$ = End-Diastolic Volume (volume of blood in the ventricle at the end of filling)
$ESV$ = End-Systolic Volume (volume of blood remaining in the ventricle after contraction)
SV represents the actual amount of blood pumped by the heart per beat.
