Standardization 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 کاملStandardization in the measurement of left ventricular wall mass. Two-dimensional echocardiography.
Two-dimensional echocardiography is superior to M-mode echocardiography for estimation of left ventricular mass when left ventricular shape is markedly abnormal. Left ventricular mass measurement by two-dimensional echocardiography depends on careful experimental calibration of the echocardiographic instrument using either a standard phantom or actual heart slices, and appropriate geometric alg...
متن کاملEchocardiography in the Measurement of Left Ventricular Wall Mass
THE purpose of this supplement is to define the current status and future applications of echocardiography in hypertension research. Electrocardiography has long been used in epidemiologic studies of hypertrophy and its regression." More recently, however, mounting evidence of the superior precision, reproducibility, sensitivity, and specificity of echocardiography as a noninvasive tool for mea...

same variables in corresponding patients. The echo-measured left ventricular enddiastolic chamber dimension (Dd) correlated closely with the angiographic minor axis in the AP plane (correlation coefficient 0.87 and SE -+-0.45 cm) and with the minor axis from the lateral film (r 0.91, SE +0.39 cm). Similar correlations were found between measurements by these methods of wall thickness (r = 0.89,...
متن کاملInfluence of measurement inaccuracies on determination of left ventricular mass by M mode echocardiography.
OBJECTIVE To determine to what extent inaccuracies in measuring the end diastolic diameter of the left ventricle, the interventricular septum, and the posterior wall, by M mode echocardiography influence the left ventricular mass calculated by the Devereux's formula. DESIGN Mathematical model. RESULTS Relatively small measurement inaccuracies such as 5%, which are known to be inherent in th...
