Figure 1.
Correlation between electrocardiographic LVH and left ventricular mass index (LVMI).
(A) Sokolow-Lyon voltage (SV), Cornell voltage (CV), (B) Sokolow-Lyon voltage-duration product (SP), and Cornell voltage-duration product (CP) correlated significantly with LVMI. Data are correlation coefficients (r).
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.
Figure 3.
Kaplan-Meier curves for cardiovascular survival.
Compared to patients without electrocardiographic LVH, the 5-year cardiovascular survival rates were significantly lower in patients with electrocardiographic LVH based on (A) Sokolow-Lyon voltage (SV), (B) Sokolow-Lyon voltage-duration product (SP), (C) Cornell voltage (CV), and (D) Cornell voltage-duration product criteria (CP).
Figure 4.
ROC curve analysis for cardiovascular mortality.
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 68.1%, 72.3%, 64.2%, and 76.0%, respectively.
