The effect of residual noise on the reproducibility of the signal-averaged electrocardiogram.
Signal averaging reduces noise in the surface ECG, allowing late potential identification. However, late potentials may vary within a patient from study to study. In a population with stable biopotentials, this work evaluated how residual noise (RN) affects signal-averaged ECG (SA-ECG) reproducibility.
