|
Typical value | Normal range |
|---|---|---|
| end-diastolic volume (EDV) | 120 mL | 65–240 mL |
| end-systolic volume (ESV) | 50 mL | 16–143 mL |
| stroke volume (SV) | 70 mL | 55–100 mL |
| ejection fraction (Ef) | 58% | 55–70% |
| heart rate (HR) | 75 bpm | 60–100 bpm |
| cardiac output (CO) | 5.25 L/minute | 4.0–8.0 L/min |
Its value is obtained by subtracting end-systolic volume (ESV) from end-diastolic volume (EDV) for a given ventricle.
In a healthy 70-kg man, EDV is approximately 120 mL and ESV is approximately 50 mL, giving a difference of 70 mL for the stroke volume.
"Stroke work" refers to the work, or pressure of the blood ("P") multiplied by the stroke volume.

“Common sense is the measure of the possible; it is composed of experience and prevision; it is calculation appled to life.”
—Henri-Frédéric Amiel (1821–1881)
““To my thinking” boomed the Professor, begging the question as usual, “the greatest triumph of the human mind was the calculation of Neptune from the observed vagaries of the orbit of Uranus.”
“And yours,” said the P.B.”
—Samuel Beckett (1906–1989)
