Figure 2. ROC curve analysis for echocardiographic LVH.
The ROC curve was constructed by plotting the sensitivity (true positive rate) vs. 1-specificity (false positive rate) for each ECG-LVH criterion. At the highest predicted probability, sensitivities of Sokolow-Lyon voltage (SV), Sokolow-Lyon voltage-duration product (SP), Cornell voltage (CV), and Cornell voltage-duration product (CP) were 27.1%, 40.8%, 32.6%, and 45.9%, respectively.
