ABSTRACT:
Cardiac electrical stability is assessed by generating a measure of cardiac electrical stability (e.g., an alternans measure) using a physiologic signal representative of activity of a patient's heart, generating a reference signal that provides information regarding whether the measure is representative of cardiac electrical stability, and visually presenting the measure and the reference signal in a way that permits visual evaluation of whether the measure is representative of cardiac electrical stability in view of characteristics of the reference signal.
