 This criterium 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 specicity of 88% for echocardiographically measured LVH<cite>echo</cite><cite>echo2</cite>. Moreover, both are independent estimators of worse prognosis.<cite>sundstrom</cite>.
-Other criteria:
-*R >26 mm in V5 or V6;
-*R >20 mm in I, II or III;
-*R >12 mm in aVL (in the absence of [[Conduction delay#LAFB|left anterior fascicular block]]);
 The '''Cornell-criterium''' has different values in men and women:
 * R in aVL and S in V3 >28 mm in men
 * R in aVL and S in V3 >20 mm in women

 In the '''Romhilt-Estes Score''' LVH is ''likely'' with 4 or more points. LVH is ''present'' with 5 or more points:
