Signal-averaged electrocardiography is a valuable tool with high negative predictive value for ruling out malignant ventricular arrhythmias after myocardial infarction.
Jarrett et al. (1991) conducted a review in Myocardial infarction, ventricular arrhythmias, syncope. Signal-averaged electrocardiography (SAECG) was evaluated on Prediction of malignant ventricular arrhythmias after myocardial infarction. Signal-averaged electrocardiography has a high negative predictive value (96-99%) for predicting the absence of malignant ventricular arrhythmias after myocardial infarction.
