Precordial SAECG may identify higher arrhythmic risk post-MI; leaves open incremental value over LVEF in prospective studies.
Does signal-averaged ECG with precordial configuration better predict arrhythmic events compared to XYZ configuration in patients recovering from acute myocardial infarction?
Precordial configuration signal-averaged ECG, especially when combined with ejection fraction, significantly predicts arrhythmic events after acute myocardial infarction.
Strasberg et al. (1993) studied this question.
