An analysis of electrocardiographic criteria for determining left ventricular hypertrophy
Rev Bras Hipert ; 4: Pediatr Cardiol ; The study by Fogel et al 49 pointed this finding out. Standardization of M-mode echocardiographic left ventricular anatomic measurements. The patient universe comprised normal individuals and those whose echocardiograms showed increased left ventricular criteris 19 women and 21 men had undergone valve replacement mostly of the mitral valve; 5 women and 8 men had metallic prostheses.
Heart rate variability in left ventricular criteriks. In contrast with earlier tracings, no significant variation due to age was noted, values remaining constant in the diverse age groups Figure 2when LVM was corrected for body surface. The degree of agreement in the methods was analyzed separately for male and female patients. A method of comparing the areas under receiver operating characteristic ROC curves derived from the same cases. The application of equations taking into consideration anthropometric measurements has also been amply analyzed Prognostic implications of echocardiographically determined left ventricular mass in the Framingham Heart Study.

Aging leads to a reduction in QRS complex amplitude, soklow can decrease the electrocardiographic sensitivity Angiotensinogen T allele dosage is associated with blood pressure phenotypes. Schillaci G, Porcellati C. N Engl J Med ; 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.
Few reports exist in the critrrios of sensitivity and specificity values of this index. New sex dependent normal limits of signal averaged electrocardiogram. Validity of electrocardiographic criteria criterois left ventricular hypertrophy in children with pressure – or volume – loaded ventricles: In males, decreased average amplitudes were observed with increasing age, both in individuals with or without ventricular hypertrophy, except for a progressive increase in average amplitude based on the Cornell criterion, noted in normal subjects.
This was exactly the opposite of what had been proposed by Casale et al 10the authors who created the criterion. These results differ significantly from ours, probably due to the analysis performed by those authors involving a small cohort. Sensitivity, specificity, positive and negative predictive values of each electrocardiographic criteria and were statistically analyzed with the statistical test for 2 independent groups.
The method showing the highest sensitivity in women was Cornell’s, while in men it was Sokolow-Lyon-Rappaport’s.
J Am Coll Cardiol ; 6: Levy et al 33 point out that the echocardiogram is a reference for studies on the evaluation of electrocardiographic criteria for detection of LVH.
Running against the progressive increase in left ventricular mass with aging, a decrease in voltage amplitude of the electrocardiographic criteria analyzed occurred, suggesting xriterios drop in sensitivity of LVH detection methods with aging.
The Cornell index had greater sensitivity in women, and the Sokolow-Lyon-Rappaport index was more sensitive in men. All measurements were taken at the end of ventricular diastole, corresponding to the beginning of criyerios QRS complex recorded on the simultaneously taken electrocardiographic tracing.
The presence of ischemic cardiac disease and myocardial dilatation with ventricular hypertrophy determines the presence of irregular areas normal fibers alternating with thinned, necrotic, or inflamed fibers.
How to cite this article. Analysis of the relation between thoracic perimeter and the voltages of the 3 criteria showed a direct graphic correlation with the anterior-posterior thoracic diameter and was therefore not represented here. Echocardiographically determined left ventricular mass index in normal children, adolescents and young adults.
Finally, the study analyzed the relationship of the most sensitive electrocardiographic criteria with age, anterior-posterior thoracic critreios, thoracic perimeter, and left ventricular mass in the population of individuals considered normal, separated for male and female sex, to evaluate the influences of such variables on these methods.
An analysis of electrocardiographic criteria for determining left ventricular hypertrophy.
Feldman et al 50 demonstrated a correlation between the R wave at the V5 and V6 derivations with an increase in the cardiac chamber, confirming this assertion. In this study, we determined the electrocardiographic criterion that had the greatest sensitivity for detecting left ventricular overload in men and women.
Normalization for body size and population attributable risk of left ventricular hypertrophy: 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
