Abstract
An in-house written software package was used to generate templates of QRS complexes and T waves using self-similarity techniques, and leave a residual signal representing only atrial activity. The templating performance differences between individual ECG leads were tested. The mean number of templates in each of the 3 ECG leads was 8/spl plusmn/4, 2/spl plusmn/1, 7/spl plusmn/5 for the QRS complexes, and 11/spl plusmn/5, 11/spl plusmn/8, 10/spl plusmn/5 for the T waves. Lead 2 generated less QRS templates than 2 other leads, left less unmatched QRS complexes and T waves (all p
