A positive signal-averaged electrocardiogram (ECG)-in combination with other specific indicators-is a predictor of increased risk for sudden cardiac death.Many patients with a positive signal-averaged ECG (abnormal)display a normal signal-averaged ECG when placed on antidysrhythmic medications.The signal-averaged ECG is not analyzed in isolation.It is used in conjunction with other cardiac diagnostic tests,including the electrophysiology study (EPS).It is a helpful adjunct to the EPS but does not replace it.
