This criterion is not reliable below age 40 years.<cite>Chou</cite> In 10-29 year olds, the 99th percentile for SV1+RV5 is 53mm. In 20-39 year olds: 32% have SV2+RV5 > 35 mm.<cite>chou</cite> Correlation between LVH on ECG and echocardiography is low with ECG having a sensitivity of 27% and specificity of 88% for echocardiographically measured LVH<cite>echo</cite><cite>echo2</cite>. Moreover, both are independent estimators of worse prognosis.<cite>sundstrom</cite>. | This criterion is not reliable below age 40 years.<cite>Chou</cite> In 10-29 year olds, the 99th percentile for SV1+RV5 is 53mm.

This is a better predicting | This is a better predicting criterion than the Sokolow-Lyon criterion, but less easy to remember, and therefore less often used.<cite>Levy</cite><cite>Sundstrom</cite> | ||
In the [[Romhilt-Estes Score]] LVH is ''likely'' with 4 or more points. LVH is ''present'' with 5 or more points.<cite>Romhilt</cite> Romhilt has reviewed ECG LVH criteria and gives an overview of the many LVH scoring systems. <cite>Romhilt2</cite> Left ventricular hypertrophy has prognostic consequences as has been found in several studies.<cite>Levy</cite><cite>Sundstrom</cite> | In the [[Romhilt-Estes Score]] LVH is ''likely'' with 4 or more points.
