Overview

The principal method used to diagnose LVH is echocardiography, during which the thickness of the muscle of the heart can be measured.

Echocardiogram Findings

Two dimensional echocardiography can produce images of the left ventricle. The thickness of the left ventricle as visualized on echocardiography correlates with its actual mass. Normal thickness of the left ventricular myocardium is from 0.6 to 1.1 cm (as measured at the very end of diastole). If the myocardium is more than 1.1 cm thick, the diagnosis of LVH can be made.
