Evaluation of the reproducibility and accuracy of apex beat measurement in the detection of echocardiographic left ventricular dilation.
Abstract
OBJECTIVE: To develop a standardized method for measuring the width of the apex beat and to determine its precision and accuracy in detecting echocardiographically determined left ventricular dilation.
DESIGN: In the reproducibility study, two cardiologists blinded to each other's findings measured the apex beat. To determine accuracy, blind, independent assessment of apex beat measurement was compared with left ventricular enlargement …
