Fig. 1From: Left atrial morpho-functional remodeling in atrial fibrillation assessed by three dimensional speckle tracking echocardiography and its value in atrial fibrillation screeningAn example of motion tracking analysis of LA using 4D Auto LAQ, Echopac, GE Health. A Display of acquired LA 3D images showing apical four-chamber, two-chamber, three-chamber plane on the left and 9 slices of short-axis views from mitral annular plane to the atrial roof. B Landmark setting stage with three landmarks set at proper places according to the instruction. C Review stage with the LA endocardial contour traced. D A simulated model of reconstructed LA and output parameters. E LA strain/volume-time curveBack to article page
