Fig. 6From: A demonstration of high field-of-view stability in hands-free echocardiographySeptal longitudinal strain. a-f show representative longitudinal strain (%) curves acquired in the apical view from a single volunteer. g-h display the variability of septal longitudinal strain estimates acquired by the trained observer and of the hands-free acquisitions. Interquartile ranges are similar between both methods, although there is some variation in median valuesBack to article page
