1. A system for use in cardiac evaluation comprising:
electrode apparatus comprising a plurality of external electrodes to monitor electrical activity from tissue of a patient; and
a computing apparatus comprising processing circuitry and operably coupled to the electrode apparatus, the computing apparatus configured to:
monitor electrical activity using the plurality of external electrodes resulting in a plurality of electrode signals over a plurality of cardiac cycles,
remove at least one unsatisfactory cardiac cycle from the plurality of cardiac cycles resulting in a representative set of cardiac cycles, and
generate representative electrical heterogeneity information (EHI) based on the monitored electrical activity of the representative set of cardiac cycles.
