Describes the use of signal averaged electrocardiography to identify patients at high risk for
lethal arrhythmia. Purpose of signal averaging; Discussion on ventricular late potentials; …

Signal-averaged electrocardiography allows the detection of late potentials, which have
been associated with delayed and disorganized ventricular activation. This article reviews …

High gain, signal-averaged electrocardiography appears to be at its most powerful in the
prediction of arrhythmic events (sudden death and symptomatic, spontaneous, sustained …

Sufficient data are available to recommend the use of the high-resolution or signal-averaged
electrocardiogram in patients recovering from myocardial infarction without bundle branch …

Currently, there are three prognostic indicators of ventricular electrical instability: long-term
ambulatory ECG recording, programmed electrical stimulation and the signal-averaged …

Noninvasive techniques to detect patients at high risk for ventricular tachyarrhythmias and
prone to sudden cardiac death are strongly needed. Most patients at risk have an underlying …

In conclusion, signal-averaged electrocardiography is a useful, noninvasive technique to
identify patients after myocardial infarction at risk for future arrhythmic events, especially in …

To gain insight into the prognostic significance of the presence of late potentials detected by
body surface signal-averaged electrocardiography during acute myocardial infarction, the …

One hundred consecutive patients recovering from an acute myocardiai infarction
underwent, prior to home discharge, signal‐averaged electrocardiography (ECG), left …

The signal-averaged ECG has proven to be a valuable tool for identifying patients at risk of
ventricular arrhythmias. This computerized method of analyzing standard ECGs identifies …
