## Abstract

Various systems, methods, and devices related to modifying views of a multi-lead electrocardiogram (ECG), as well as identifying notations associated with the multi-lead ECG, are described. An example method includes displaying graphical elements in a first arrangement. The graphical elements respectively depict electrical signals indicative of an electrical activity of a heart. The example method further includes detecting a signal indicative of a display selection, and, based on the display selection, rearranging the graphical elements from the first arrangement to a second arrangement.
