Left Ventricular Stroke Work Index Calculator

Indexes left ventricular stroke work to body surface area.

Inputs

Color mode links each input to the matching equation term and solving arithmetic.

Equation and Work

Equation:
Solving steps:
LVSWI
—
g·m/beat/m²
LVSWI status
—
40–60 reference
Normal/reference: LVSWI is commonly about 40–60 g·m/beat/m².

Clinical Significance

Indexes left ventricular stroke work to body surface area.

This calculator expands that idea by identifying the relevant measured values, substituting the selected inputs, and carrying the arithmetic through in the solving steps.

Use LVSWI to compare left ventricular work among patients with different body surface area.

Calculator output should be interpreted with the patient’s condition, measurement quality, and local clinical policy.
