New Discovery of Left Atrial Macroreentry Tachycardia: Originating from the Spontaneous Scarring of Left Atrial Anterior Wall

Figure 5

The receiver operating characteristic (ROC) analysis of age and combination of gender and age for predicting the LAMRT originating from the LAAW. The area under the curve (AUC) of age and combination of gender (and age for predicting the LAMRT originating from the LAAW) were 0.918 (a) and 0.951 (b), respectively. (c) Although the comparison between the two was not statistically significant, the combination of gender and age showed a higher specificity. LAAW: left atrial anterior wall; LAMRT: left atrial macroreentry tachycardia.
