The Ventricular Volume Variability Study of the Pediatric Heart Network: Study Design and Impact of Beat Averaging and Variable Type on the Reproducibility of Echocardiographic Measurements in Children with Chronic Dilated Cardiomyopathy
Journal of the American Society of Echocardiography, 06/08/2012
Colan SD et al. – This comprehensive evaluation of quantitative echocardiographic methods will provide a valuable resource for the design of future pediatric studies. Beat averaging (BA) and a single core lab observer improve the reproducibility of echocardiographic measurements in children with dilated cardiomyopathy. Certain measurements are highly reproducible, while others, despite BA, are poorly reproducible.
