Current methods for detecting nonlinear determinism in a time series require long and
stationary data records, as most of them assume that the observed dynamics arise only from …

The purpose of this investigation was to prospectively evaluate the immediate reproducibility
of the signal-averaged electrocardiogram (SAECG). A total of 114 patients undergoing …

The prognostic significance of serial signal-averaged electrocardiograms recorded during
the first 3 days (period 1), in the second week (period 2) after a first acute myocardial …

Signal averaging principles have been utilized since around 1875. Their application in
medicine to enhance biologic signals was first made in 1947 for improved detection of …

Abstract Early reperfusion (4 to 6 hours) after acute myocardial infarction reduces mortality
and reduces the incidence of late potentials on a signal-averaged electrocardiogram …

Signal-averaged ECG has been used to identify patients at risk for ventricular tachycardia
and sudden death after myocardial infarction. The goals of this prospective study were to …

Signal-averaged electrocardiography (SAECG) is a technique involving computerized
analysis of segments of a standard surface electrocardiogram. It is used for detecting small …

Cardiac arrhythmias as cause of sudden cardiac death remains an important public health
problem. The availability of effective treatment in terms of the implantable defibrillator makes …

The aim of the study was to evaluate the immediate reproducibility of time domain
parameters in the signal averaged electrocardiogram using a new method for endpoint …

Signal‐Averaged ECG. Signal averaging of the surface QRS complex has been used in
