Romhilt DW, Estes Jr. Anatomic validation of left ventricular mass estimates from clinical two-dimensional echocardiography: Normality criteria for left ventricular mass in children were defined by the studies of Simone et al 19 and Daniels et al 20 and were in agreement with the normality curve cited by Feigenbaum 17, Various population characteristics were determined from this normal subgroup.
Validity of electrocardiographic criteria for left ventricular hypertrophy in children with critrrios – or volume – loaded ventricles: A method of comparing the areas under receiver operating characteristic ROC curves derived from the same cases. Effects of age, sex, and race on ECG interval measurements. The electrocardiographic criteria were more efficient when dilatation predominated over left ventricular hypertrophy. J Electrocardiol ; 27 suppl: Specificity was also lower than that found in the present work.
Change in ventricular cavity size: The same study 54 used in its majority as population samples cases of serious cardiac disease, with large values of ventricular mass that could have led to overestimation of the method’s sensitivity.
Left ventricular hypertrophy by electrocardiogram. Prognostic significance of serial changes in left ventricular mass in essential hypertension.
Devereux RB, Reichek N. Curiously, these were the methods that showed least sensitivity, both in men and in women. Tracings showing the correlation between Sokolow-Lyon-Rappaport, Sokolow-Lyon, and Cornell criteria with anterior-posterior diameters of the thorax are shown in Figure 4.
In this study, we determined the electrocardiographic criterion that had the greatest sensitivity for detecting left ventricular overload oskolow men and women.
The S wave of the V 3 derivation represented the electromotive force of the left ventricle, directed towards the posterior region of the thorax, observed in criterio increases in the mass of the left ventricle. The degree of agreement in the methods was analyzed separately for male and female citerios.
According to the report, left ventricle dimensions were significantly correlated with the body surface area.
New sex dependent normal limits of signal averaged criterioa. Br Heart J ; Left ventricular mass determined by echocardiography was considered as the gold standard, and results of this examination were accepted as the true ones. Our results demonstrate a lower sensitivity in 4 of the 5 electrocardiographic criteria studied in women. In males, left ventricular mass is proportionately greater than in females of the same age, weight, and body surface Normalization for body size and population attributable risk of left ventricular hypertrophy: The 3 criteria had statistically significantly higher sensitivity than those of White-Bock and Romhilt-Estes.
Isselbacher KJ, Braunwald E.
Rev Bras Ecocardiogr ; Ethnic differences in electrocardiographic criteria for left ventricular hypertrophy: Sokolow M, Lyon TP. As shown above, this similarity did not extend to mean age.
ECGs and echocardiograms of each patient were taken on the same day. The present study attempts to correlate findings obtained with 5 different ssokolow criteria with data on left ventricular mass obtained by echocardiography. Value of echocardiographic measurement of left ventricular mass in predicting cardiovascular morbid events in hypertensive men.
Aging leads to a reduction in QRS complex amplitude, which can decrease the electrocardiographic sensitivity Prognostic implications of echocardiographically determined left ventricular mass in the Framingham Heart Study. Am J Med ; Some studies use only height as a corrective criterio, but it is known that this is not a good predictor of left ventricular mass, unlike weight or body surface Sensitivity in that study was very close to sensitivity found in men in the present study.
Study of apparently normal subjects. N Engl J Med ; Questions about previous cardiac surgery and valve replacement were asked. The White-Bock and Romhilt-Estes criteria had low sensitivity but high specificity.
An updated coronary risk profile: ECGs were obtained after the clinical examination. Prevalence and natural history of electrocardiographic left ventricular hypertrophy. The Sokolow-Lyon criterion had a greater sensitivity of Eighteen criteeios and 21 women were non-Caucasian.
The type may influence the electrocardiographic findings.
