Signal‐averaged electrocardiography records delayed depolarization of myocardial areas
with slow conduction that can form the substrate for monomorphic ventricular tachycardia …

Historically, risk stratification for survivors of acute myocardial infarction (AMI) has centered
on 3 principles: assessment of left ventricular function, detection of residual myocardial …

Serial recordings of the signal-averaged ECG and the 24-hour ambulatory ECG were
obtained from 156 patients with acute myocardial infarction up to 5 days (phase 1), 6 to 30 …

Objectives. This study assessed the ability of signal-averaged electrocardiography,
radionuclide ventriculography and Holter electrocardiographic (ECG) monitoring and clinical …

Objective To investigate the accuracy of signal averaged electrocardiography (SAECG) and
measurement of microvolt level T wave alternans as predictors of susceptibility to ventricular …

Experimental studies indicate that oxygen-free radicals contribute to ischemic myocardial
damage and affect electric properties of cellular membranes. We hypothesize that an …

After the signal-averaging process is completed, the result is usually stored on a disk file for
subsequent analysis. A few investigators have assessed SAECG data visually. Most authors …

The prevalence of an abnormal signal-averaged electrocardiogram (ECG) and ventricular
arrhythmias on 24 h ambulatory electrocardiography was evaluated in 118 patients 13±2 …

BACKGROUND Signal-averaged ECG is a noninvasive test designed to detect" late
potentials." The effects of alterations in autonomic tone on the signal-averaged ECG have …

The relation between transient myocardial ischemia and late potentials was investigated in
100 patients with coronary artery disease who underwent serial recordings of the signal …
