Evaluation of Left Atrial Function in Patients with Paroxysmal Atrial Fibrillation Using Left Atrial Automatic Myocardial Functional Imaging Ultrasonography

Figure 2

Comparison of ROC curves of left atrial volume and strain parameters in patients with atrial fibrillation. (a) The ROC curve of LAVmax (left atrial maximum volume) test for atrial fibrillation; (b) the ROC curve of LAVmin (left atrial minimum volume) test for atrial fibrillation; (c) the ROC curve of LAEF (left atrial emptying fraction) to test atrial fibrillation; (d) the ROC curve of LAVPreA (left atrial volume before systole) test for atrial fibrillation; (e) the ROC curve of S_ R (left atrial reservoir period strain) test for atrial fibrillation; (f) the ROC curve of S_CD (left atrial conduit strain) for testing atrial fibrillation; (g) the ROC curve of S_CT (left atrial contractile strain) test for atrial fibrillation.
