Left ventricular dimensions calculator and measurement guide
Explore left ventricular linear measurements, their acquisition guidance and the reference context available in the tool.
Method
Indexed diameter = LVID ÷ BSA
Use the measurement units shown below. Some fields apply only to a selected method or condition; follow the interactive tool’s method choices. The interactive tool keeps missing measurements incomplete and provides its method-specific results and reference context.
