Critical analysis of the signal-averaged electrocardiogram. Improved identification of late potentials.
BACKGROUND This study performed a critical analysis of signal-averaging methods. The objective was to optimize detection of late potentials. METHODS AND RESULTS We studied two patient populations: a low-arrhythmia-risk group with no evidence of heart disease and a group with clinically documented ventricular tachycardia (VT). Filtered QRS duration (QRSD) and terminal QRS amplitude (RMS40) wer...

متن کاملTime domain analysis of the signal averaged electrocardiogram to detect late potentials in heart failure patients with different etiologies.
OBJECTIVE To evaluate the frequency, clinical correlations and prognosis influence of late potentials on the of heart failure patients with different etiologies using the signal averaged electrocardiogram. METHODS A 42 month study of the signal averaged electrocardiograms of 288 heart failure patients with different etiologies was conducted. The group of patients included 215 males (74.65%) a...

متن کاملSignal-averaged electrocardiogram. Improved identification of patients with ventricular tachycardia using a 28-lead optimal array.
BACKGROUND Although the signal-averaged ECG (SAECG) is currently the best noninvasive test to identify patients with ventricular tachycardia (VT) following myocardial infarction (MI), it is still a relatively insensitive test. Body surface mapping has improved the sensitivity of ECG in detecting various cardiac diseases. This study applied body surface mapping to the SAECG in the form of a clin...
