1. A system for use in cardiac evaluation comprising:
- electrode apparatus comprising a plurality of external electrodes to be located proximate a patient'"'"'s skin, wherein the plurality of external electrodes comprises;
a posterior set of electrodes located proximate the patient'"'"'s posterior, andan anterior set of electrodes located proximate the patient'"'"'s anterior;
a display comprising a graphical user interface to present cardiac signal information; and
computing apparatus comprising processing circuitry, the computing apparatus operably coupled to the electrode apparatus and the display, the computing apparatus configured to;
monitor electrical activity from the patient'"'"'s skin using the plurality of external electrodes over a cardiac cycle resulting in a posterior set of electrode signals monitored from one or more of the posterior set of electrodes and an anterior set of electrode signals monitored from one or more of the anterior set of electrodes, wherein the posterior set of electrode signals and anterior set of electrode signals are representative of cardiac activity,process the posterior set of electrode signals and the anterior set of electrode signals for at least one cardiac cycle, anddisplay on the graphical user interface the posterior set of electrode signals and the anterior set of electrode signals on a single-cycle graph, wherein the anterior set of electrode signals are graphically distinguishable from the posterior set of electrode signals.

Abstract
The exemplary systems, methods, and interfaces may obtain and analyze electrode signals from a plurality of external electrodes. The electrode signals may include at least an anterior set of electrode signals and a posterior set of electrode signals. The anterior and posterior sets of electrode signals may be used to generate, or provide, various metrics of cardiac electrical heterogeneity and various graphical depictions that may be useful in assessing a patient'"'"'s cardiac functionality.
