LVH is often seen in patients with long-standing uncontrolled hypertension.
If the sum of the S wave in lead V1 and the R wave in lead V5 or V6 is ³35 mm or the R wave in aVL is ³11 mm, it suggests the presence of LVH (Sokolow-Lyon indices).
“The sensitivity of an EKG for LVH ranges from 7% to 50%, however, so echocardiography is the test of choice to make the diagnosis. Echocardiography helps to directly visualize and quantify left ventricle wall size, in addition to providing other valuable information such as cardiac wall motion abnormalities, ejection fraction, and cardiac chamber dimensions. There is no primary role for the other tests listed in this setting (SOR B).” ABFM
“The diagnosis and treatment of left ventricular hypertrophy (LVH) in patients with hypertension is important, as it is associated with increased morbidity and mortality from heart failure, arrhythmias, and sudden cardiac death.”
