Stroke Volume Calculator

Estimate stroke volume from cardiac output and heart rate or from EDV−ESV.

Stroke Volume

Estimate stroke volume (mL/beat) from cardiac output and heart rate.

Understanding the Inputs

Use consistent, rested conditions when possible

Cardiac Output (L/min): Total blood volume pumped by the heart each minute.
Heart Rate (bpm): Beats per minute at the time of the cardiac output measurement.

Complete Guide: Stroke Volume in Context

Stroke volume interacts with heart rate and vascular resistance to determine cardiac output. Training, hydration, and recovery all shape these variables. Use this estimate to inform, not replace, professional assessment.

Frequently Asked Questions

Detailed, SEO-oriented answers

What is stroke volume?

Stroke volume (SV) is the amount of blood pumped from the left ventricle per heartbeat.

How do I calculate SV?

SV = Cardiac Output (L/min) × 1000 ÷ Heart Rate (bpm). This calculator performs that conversion.

What are typical SV values?

At rest, SV commonly ranges from ~60–100 mL/beat, varying by size and fitness.

Does training increase SV?

Endurance training often increases stroke volume and reduces resting HR.

How accurate is this?

SV typically requires clinical tools for precise measurement. This is an educational estimate based on provided values.

Why does hydration matter?

Dehydration reduces plasma volume, potentially lowering stroke volume.

Can medications affect SV?

Yes—cardiac medications and conditions alter HR and contractility, affecting SV and CO.

When should I re-check?

Reassess after training blocks or when changing routines that affect cardiovascular status.

Is a very high SV good?

Context matters. Consult a clinician to interpret unusually high or low values.

Is this medical advice?

No—educational only. Seek professional evaluation for health concerns.
