Reliability of Visual Assessment of Global and Segmental Left Ventricular Function: A Multicenter Study by the Israeli Echocardiography Research Group

Among experienced readers using contemporary echocardiographic equipment, interobserver and intraobserver reliability was reasonable for the visual quantification of normal and akinetic segments but poor for hypokinetic segments. Reliability was good for the visual assessment of global left ventricular function by WM score index and ejection fraction.
