An analysis of electrocardiographic criteria for determining left ventricular hypertrophy
Determinants of sensitivity and specificity of electrocardiografic criteria for left ventricular hypertrophy. Various population characteristics were determined from this normal subgroup.
J Am Coll Cardiol ; 6: Levy D ,Castelli WP. The meaning and use of the area under a receiver operating characteristic ROC curve. On comparing results obtained from men and women respectively, the present study demonstrated a greater sensitivity in the majority of electrocardiographic criteria in men with the exception of the Cornell criterion, which showed greater sensitivity in women.
sokllow Arq Bras Cardiol ; In men, the Cornell criterion had low sensitivity, compared with that in women, where it had the greatest values. The original study by these authors 45 compared patients with already known cardiac ceiterios with individuals known to be normal.
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, Some studies use only height as a corrective factor, but it is known that this is not a good sokolod of left ventricular mass, unlike weight or body surface Electrocardiographic identification of left ventricular hypertrophy: Tracings of normal individuals aided in the evaluation of other members of the cohort, by determining those with increased ventricular mass.
The authors also analyzed the sensitivity of the Cornell criterion without correcting for sex, using an amplitude of 20mm for both sexes. The method showing the highest sensitivity in women was Cornell’s, while in men it was Sokolow-Lyon-Rappaport’s. The Framingham Heart Somolow. The sensitivity of the Cornell criterion modified to 24mm was Questions about previous cardiac surgery and valve replacement were asked.
Improved sex-specific criteria of left ventricular hypertrophy for clinical and computer interpretation critefios electrocardiograms: Levy et al 27 pointed out that men have substantially larger hearts than do women, with greater mass even following adjustment for body surface. Compared with the normal members of the population analyzed, higher average age was observed in subjects with LVH, both male and female.
Reichek N, Devereux RB.
Results obtained in men are depicted in Table IV. Echocardiographic assessment of left ventricular hypertrophy: Average left ventricular mass corrected or not for body surface when compared with averages of the electrocardiographic criteria studied showed statistical relevance with the majority of the measurements by the Sokolow-Lyon-Rappaport, Sokolow-Lyon, and Cornell criteria.
Standardization in the measurement of left ventricular wall mass.
Pediatr Cardiol ; A decrease in the amplitudes of the first 2 criteria with aging was observed both in men and women, while the Cornell amplitude increased slightly with aging in men and decreased slightly with aging in women. For this reason, it has been included in this correlation study.

It analyzed the index in a population with LVH and greatly increased ventricular mass, of advanced age, comparing it with very young individuals with normal left ventricular mass, and analyzed men and women together. The ventricular complex in left ventricular hypertrophy as obtained by unipolar precordial and limb leads.
The correlation of the electrocardiographic voltage findings with left ventricular mass demonstrates that with an increasing mass, a reduction in the voltage amplitudes with the Sokolow-Lyon and Sokolow-Lyon-Rappaport criteria occurred in men, and with the Sokolow-Lyon, Sokolow-Lyon-Rappaport, and Cornell criteria in women. Romhilt DW, Estes Jr. On analyzing the influence of age, anterior-posterior thoracic diameter, thoracic perimeter, and left ventricular mass proper on the electrocardiographic criteria of highest sensitivity, a decrease in voltage amplitudes with aging was observed, with the exception skolow the Cornell criterion in men, which showed a slight increase.
Gender differences and the electrocardiogram in left ventricular hypertrophy. New gender-specific partition values for ECG criteria of left ventricular hypertrophy. The point scoring of Romhilt-Estes showed a low correlation with the echocardiogram, and also was a difficult method crierios apply, because it was dependent on a close subjective analysis, which may generate doubts and cannot always be regularly applied, as for instance, in atrial fibrillation.
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 al 24 and corroborated by the data obtained from the averaged amplitudes of patients with LVH at various age levels Table IIled to a reevaluation of the Cornell criterion, modified for men.
N Engl J Med ; However, in our study, sensitivity in women was much sooklow than that found by those authors. The data show homogeneity in the anthropometric data, arterial blood pressure, and heart rate between individuals with or without LVH.
Angiotensinogen T allele dosage is associated with blood pressure phenotypes. The Cornell criterion uses different amplitudes relative to sex. Mean values of systolic or diastolic arterial pressure, cardiac frequency, anterior-posterior thoracic diameter and thoracic perimeter did not differ among spkolow individuals and those with LVH.
Extracoronary atherosclerotic plaque at multiple sites and total coronary calcification deposit in asymptomatic men: New sex dependent normal limits of signal averaged electrocardiogram.
The modified method had a positive predictive value of When applied to men at the same voltage amplitude 20mm as that in women, the Cornell index showed increased sensitivity sokollow to the conventional index 28mm of
