Fig. 2From: Echocardiographic reference ranges for noninvasive left ventricular 18-segment myocardial work index and work efficiency in a healthy Asian populationA 18-segment bull's-eye diagram shows the functional nonuniformity of the myocardial work index in the normal left ventricle. The values in the different segments are mean values. B 18-segment bull's-eye diagram shows the functional nonuniformity of myocardial work efficiency in the normal left ventricle. The values in the different segments are median valuesBack to article page
