Test characteristics of clinical electrocardiogram (ECG) rules vs deep learning models for classification of left ventricular hypertrophy (LVH) etiology vs no LVH at equivalent specificity. Grouped bar plot of sensitivity and positive predictive value (PPV) for classification of LVH etiology and echocardiographic LVH vs no LVH by clinical ECG LVH rules (blue) and LVH-Net (red). LVH-Net test characteristics were calculated at the probability cutoff that yielded a specificity equal to the specificity of the clinical ECG LVH rules. The specificity of the clinical ECG rules is shown above each facet, along with the number of cases in the validation sample. Error bars represent 95% confidence interval.
