Abstract
The term “signal averaged electrocardiogram” (SAECG) encompasses any technique that results in an improvement of the signal-to-noise ratio, thus allowing analysis of signals that are too small to be detected by routine measurement. Among such signals are those arising from areas of slow and inhomogeneous conduction in diseased ventricular myocardium [usually referred to as late potentials (LPs)]. These potentials are small because the activation front is slow and fractionated, or the mass of tissue undergoing depolarization is small, or both. Late potentials are of clinical relevance because they may identify a substrate for reentrant ventricular excitation.1
