A review of the role of electrocardiography in the diagnosis of left ventricular hypertrophy in hypertension.

ECG remains the first line method for detection of left ventricular hypertrophy (LVH) in patients with hypertension. ECG diagnosis of LVH predicts a several-fold increase in age- and risk factor-adjusted cardiovascular morbidity and mortality in asymptomatic patients with essential hypertension. When compared with traditional ECG methods, Cornell voltage product and multifactorial criteria such as the Perugia criterion allow detection of LVH in a higher proportion of subjects while carrying a high attributable risk for cardiovascular morbidity and mortality. Hence, traditional interpretation of standard ECG maintains an important role for cardiovascular risk stratification in hypertension.
