# Left Ventricular Stroke Work Index (LVSWI) Calculator

Stroke work index refers to the total work done by the heart at each of its contraction, adjusted for body surface area. Left ventricular stroke work index (LVSWI) is the tool used in the measurement of pumping function of the left ventricle based on the body size. The normal stroke work index should range between 40 to 75gm/m/beat/m2. Use this simple online Left Ventricular Stroke Work Index (LVSWI) Calculator to find the LVSWI value for a patient.

#### Formula:

BSA = 0.007184 × W^{0.425} × H^{0.725}
L = ((S - P) × V × 0.0136) / BSA
**Where,**
L = Left ventricular stroke work index (LVSWI )
P = Pulmonary artery occlusion pressure
S = Mean Arterial Pressure
V = Stroke volume
W = Patient weight(kg)
H = Patient height(cm)
This Left Ventricular Stroke Work Index (LVSWI) Calculation represents the work performed by the ventricle to eject the stroke volume into the aorta. The factor 0.0136 used in this LVSWI calculator corrects pressure and volume to units of work.
