Figure 3.

Performance of deep learning in ten-fold cross-validation for PSVT classification. (Upper row) Comparison of the model with and without pre-training, including (a) receiver operating curves (AUROCs) and (b) precision-recall curves (AUPRCs). (Lower row) Comparison of the model using different sets of leads, including (c) receiver operating curves (AUROCs) and (d) precision-recall curves (AUPRCs). AUPRC: area under the precision-recall curve; AUROC: area under the receiver operating characteristic curve; ECG: electrocardiogram.
