From: Automated multilabel diagnosis on electrocardiographic images and signals

Average of the Gradient weighted Class Activation Maps (Grad-CAMs) for the 25 most confident predictions of right bundle branch block (RBBB) and left bundle branch block (LBBB) on standard and alternate format images. A RBBB in standard format, B RBBB in alternate format, C LBBB in standard format, and D LBBB in alternate format.
