Model sensitivity and saliency map analysis. (A): A saliency-map analysis showing that over 95% of the samples in the test set ECGs with the highest saliency score occur within 400 ms of the subsequent R-peak. (B): Model output as a function of changes to the ECG, indicating that the model output is most sensitive to changes in the P-wave amplitude.
