Measurement of left ventricular wall thickness and mass by echocardiography.

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, SE +1.3 mm), of end-diastolic volume (r 0.94, SE ±30.6 cc), and of left ventricular mass (r 0.88,
