Abstract
BACKGROUND: Several ECG criteria have been widely used for diagnosis of left ventricular hypertrophy (LVH) in clinical practice. However, their performance in a general Chinese population is limited. METHODS ANDEntities:

FIGURE 2Area under the ROC Curve (AUC) and correlation between the main ECG‐LVH criteria or single lead and Echo‐LVH. BSA indexed LVM (LVMI) was applied for determination of Echo‐LVH. AUC and 95% confidence interval (95% CI), as well as correlation, were presented to evaluate the discrimination ability of ECG‐LVH criteria to identify Echo‐LVH

ECG‐LVH, electrocardiographic left ventricular hypertrophy. PPV: positive predictive values. NPV: negative predictive values
Accuracy was defined as the percentage of correctly classified instances (True Positive Rate + True Negative Rate)/(True Positive Rate + True Negative Rate + False Positive Rate + False Negative Rate)
p < .05: P value stands for pair‐wise comparison of sensitivity, specificity, PPV, NPV or accuracy between ECG criteria using Fisher's Exact test, where Peguero–Lo Presti taken as the reference.
