(a) Both inputs of entire 12-lead ECG and discrete heartbeats separated from 12-lead ECG were used to train AI Models with different architectures. All logit values from discrete heartbeats were averaged to represent the final logit value for the 12-lead ECG. Optimal thresholds were determined in the validation phase and then were saved along with the model weights; (b) test phase loaded model weights and threshold value that were saved in the training phase, then evaluated the ECG as T-NSR or CIA-NSR by comparing the threshold value and the final logit value.
