Claim 32:
33. 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 invalid signals from the plurality of electrode signals over the plurality of cardiac cycles resulting in a plurality of valid electrode signals over the plurality of cardiac cycles,
remove unqualified cardiac cycles from the plurality of cardiac cycles based on the plurality of valid electrode signals over the plurality of cardiac cycles resulting in a qualified set of cardiac cycles,
remove uncorrelated cardiac cycles from the qualified set of cardiac cycles based on the plurality of valid electrode signals over the qualified set of cardiac cycles resulting in a correlated set of cardiac cycles, and
remove inconsistent cardiac cycles from the correlated set of cardiac cycles based on the plurality of valid electrode signals over the correlated set of cardiac cycles resulting in a representative set of cardiac cycles.
