Time-domain averaging is a computer-driven sequential digital process based on the vector analysis of three orthogonal ECG leads (X, Y, and Z) that separates and extracts high-frequency late potentials from lower frequency ST segments by the use of directional filters, enabling filter output to correspond in time to signal input.
It is known that late potentials are seen more frequently in post MI patients that have spontaneous or induced sustained ventricular tachycardia.
Signal averaged ECG (SAECG): Signal-averaged ECG has shown a significant correlation between presence of late potentials and occurrence of sustained VT (73,74).
Arrhythmic evaluation by 24 h Holter ECG, measurement of ventricular late potentials and heart rate variability have been suggested for risk stratification and programmed ventricular electrophysiological stimulation has a relatively high predictive value for spontaneous ventricular tachyarrhythmias in selected groups of patients with myocarditis (12).
Late potentials were not present at signal averaged ECG recording.
