Fig. 3From: Assessment of left atrial function in feline hypertrophic cardiomyopathy by using two- dimensional speckle tracking echocardiographyThe image of the left apical four-chamber view of the left atrial strain profile of a hypertrophic cardiomyopathy cat. A region of interest is manually drawn to include the left atrial wall. The automatic software system divided the left atrial wall into 6 different segments with different colors. A white dotted line is presented as the mean of strain value of the left atrium. LA=left atrium; LV= left ventricle; PALS= peak atrial longitudinal strain (white arrow); RA= right atrium; RV= right ventricleBack to article page
