Overview

SAECG may support post-MI arrhythmia risk stratification; leaves open routine adoption pending higher-level validation.

Structured PICO

Does Signal-Averaged ECG (SAECG) predict life-threatening tachyarrhythmias in patients surviving acute myocardial infarction?

P
Population
Patients surviving acute myocardial infarction, and patients with unexplained syncope or sustained ventricular tachycardia
I
Intervention
Signal-Averaged ECG (SAECG) to detect low amplitude, high frequency components in the terminal QRS complex (late potentials)
O
Outcome
Prediction of life-threatening ventricular tachyarrhythmias and/or sudden death

This review outlines the methodology and clinical applications of Signal-Averaged ECG for identifying post-infarction patients at high risk for life-threatening arrhythmias.
