Detection of left ventricular hypertrophy by M-mode echocardiography. Anatomic validation, standardization, and comparison to other methods.
Because of its simplicity, widespread availability, relatively low cost, and lack of adverse effects, M-mode echocardiography has become the most widely used technique for measurement of human left ventricular mass. Necropsy comparison studies have yielded formulas for anatomically accurate estimation of left ventricular mass in patients with normally shaped ventricles using left ventricular me...
متن کاملReproducibility of echocardiographic left ventricular measurements.
Serial echocardiograms with acceptable reproducibility of measurements may be produced by careful performance and interpretation of the studies. The following recommendations have been shown to enhance reproducibility. Strict adherence to quality control is necessary to generate echocardiograms of the highest technical quality. Sonographers should be aware of the definition of a technically ade...
متن کاملLeft ventricular hypertrophy: relationship of anatomic, echocardiographic and electrocardiographic findings.
Anatomic, echocardiographic and ECG findings of left ventricular hypertrophy (LVH) were compared in 34 subjects. Echocardiographic LV mass correlated weel with postmortem LV weight (r = 0.96) and accurately diagnosed LVH (sensitivity 93%, specificity 95%). In contrast, Romhilt-Estes (RE) point score and Sokolow-Lyon (SL) voltage criteria for ECG LVH were insensitive (50% and 21%, respectively) ...
متن کاملStandardization in the measurement of left ventricular wall mass. M-mode echocardiography.
A wide variety of approaches to M-mode echocardiographic methods for estimation of left ventricular mass have been proposed and employed in hypertensive heart disease. The cube function geometry, which assumes an ellipsoid of revolution with a length twice the minor axis, appears to be optimal provided left ventricular shape is relatively normal. The Penn measurement technique for wall thicknes...
متن کاملAccuracy and reproducibility of new M-mode echocardiographic recommendations for measuring left ventricular dimensions.
In order to assess the accuracy and reproducibility of the proposed American Society of Echocardiography (ASE) method for measuring left ventricular dimensions on M-mode echocardiograms, we measured the end-diastolic (Dd) and end-systolic (Ds) dimensions by the ASE method and our current technique in 50 normal subjects and 24 patients without coronary artery disease who had symmetrically contra...
