The investigators defined LVH as a typical strain pattern or the product of Cornell voltage (R-wave height in lead aVL plus S-wave depth in lead V3) by body mass index >604 mm.kg/m2 They compared this to other traditional diagnostic criteria (Romhilt-Estes point score, Sokolow-Lyon, Cornell voltages, and Perugia score) and reported that the new method improves the sensitivity without affecting the already high specificity of the existing methods.
