Publisher Correction: Cardiologist-level arrhythmia detection and classification in ambulatory electrocardiograms using a deep neural network.

In the version of this article originally published, the x axis labels in Fig. 1a were incorrect. The labels originally were 'Specificity,' but should have been '1 - Specificity.' Also, the x axis label in Fig. 2b was incorrect. It was originally 'DNN predicted label,' but should have been 'Average cardiologist label.' The errors have been corrected in the PDF and HTML versions of this article.
