Notes:
BackgroundAtrial fibrillation is the most common arrhythmia encountered in clinical practice. Identification of factors predisposing to atrial fibrillation may have implications for its prevention and may facilitate the detection of patients most susceptible to atrial fibrillation and its sequelae. Prolongation of P wave duration representing intra-atrial conduction delay is inadequately visualized in a standard electrocardiogram. Accurate detection, alignment, amplification and filtering of P waves during the signal averaging process permits a better analysis of the P wave and thus atrial conduction. Signal averaged P wave electrocardiography is a noninvasive technique that has permitted the evaluation of patients at risk of developing atrial fibrillation. Several studies have correlated the abnormalities in signal averaged P wave with paroxysmal atrial fibrillation, and have demonstrated its utility in independently predicting patients at risk of developing atrial fibrillation following cardiac surgery. New uses are likely to evolve as the technique is used clinically and as the methodology is standardized. A.N.E. 1999;4(4):401–407
