The electrocardiogram has been used to indicate the degree of severity of left ventricular hypertrophy.
Analysis of this criterion, reducing the amplitude obtained by adding the voltages of the R wave in the aVL derivation to the S wave on derivation V 3 from 28 to 24mm, as proposed by Verdecchia et sokolo 24 and corroborated by the data obtained from the averaged amplitudes of patients with LVH at various age levels Table IIcriherios to a reevaluation of the Cornell criterion, modified for men. Dubois D, Dubois EF.
Left ventricular mass determined by echocardiography was chosen as the gold standard for determining LVH to be used for the comparison with electrocardiographic data, because various previous reports showed a good correlation between this method and necropsy data Electrocardiographic evidence of left ventricular hypertrophy is one of the most widely used markers of cardiovascular morbidity and mortality 3,4. Comparison of the analytical results with the patient’s identity were performed only after all data had been collected.
The Sokolow-Lyon-Rappaport index had a statistically significant sensitivity relative to all other criteria in men. Verdeccia et al 24 pointed out that sensitivity increases the greater the LVH. Casale et al 53 analyzed the Cornell criterion developed by the authors in criteios, men and women, in comparison with pre-existing criteria and compared electrocardiographic criteria with findings at necropsy.
Age, sex, race, results of the clinical examination, arterial pressure, weight, height, thoracic anterior-posterior diameter, and thoracic perimeter at the height of the fifth intercostal space were recorded. ECGs were numbered randomly to prevent later identification.
Echocardiographic evidence of ventricular hypertrophy in a general aged population. Gender differences and the electrocardiogram in left ventricular hypertrophy.
Among men, normal individuals averaged Pathological hypertrophy and cardiac interstitium.
However, a statistically significant difference relative to the conventional Cornell criterion occurred at 28mm. Subjects less than 12 years of age included 34 females and 41 males.

Left ventricular mass determined by echocardiography was considered as the gold standard, and results of this examination were accepted as the true ones. This index, which for many authors is a variation of the Sokolow-Lyon index, was analyzed separately because the presence of the sum of the S wave in the V 2 derivation was not included in the original work 51, Schillaci G, Porcellati Sokolpw.
Specificity was reduced to Isselbacher KJ, Braunwald E. Study participants were considered clinically and echocardiographically normal if they were free of alterations in the cardiac chambers, valve changes of hemodynamic significance, a transvalvular gradient detectable by color flow Doppler, had a systolic arterial pressure below mmHg and dokolow diastolic pressure below 90mmHg, had no abnormalities on clinical examination, and were not using medication.
Role of Anthropometric indexes and blood pressure as determinants of left ventricular mass and geometry in adolescents. J Electrocardiol ; 20 suppl: These authors chose the aVL and V 3 derivations to compose this index after analyzing the relation of the amplitudes of the voltages to LVH.
Electrocardiographic detection of left ventricular hypertrophy by the simple QRS voltage duration product. N Engl J Med ; The Sokolow-Lyon voltage, Sokolow-Lyon-Rappaport, Cornell voltage duration product, White-Bock, and Romhilt-Estes point scoring criteria were compared with left ventricular mass index, corrected for body surface, obtained from the echocardiograms of outpatients females, malesof all age groups.
Which definition for echocardiographic left ventricular hypertrophy? J Am Coll Cardiol ; The various results of the determinations of left ventricular hypertrophy obtained by the electrocardiographic criteria applied to each case were compared with the left ventricular mass obtained by echocardiography. The S wave of the derivation had greater voltages at the large axial deviations to the left of QRS, which is rarely seen in cases with light to moderate hypertrophy.
ECGs were obtained after the clinical examination.
An analysis of electrocardiographic criteria for determining left ventricular hypertrophy
Echocardiographically detected left ventricular hypertrophy: Devereux RB, Reicheck N. Finally, the study analyzed the relation between voltage of the Sokolow-Lyon-Rappaport, Sokolow-Lyon, and Cornell criteria, with left ventricular mass obtained by echocardiography in individuals within the range of normality.
This was also observed by the Sokolow-Lyon-Rappaport criterion in men.
