Abstract
Echocardiographic studies do not have criteria for the reproducibility of dimensions. To document significant differences within an individual, either following surgical intervention or with progression of disease; or to estimate the number of subjects required for epidemiologic studies, the magnitude of measurement error must be known. Three variables must be quantitated: 1) within observer error, 2) between observer error, 3) technical consistency. Echocardiographic dimensions must have clearly defined interfaces to be acceptable for analysis.
