Abstract

A program for the analysis of 12 simultaneous ECG leads during exercise test has been set up. It computes 12 average cycles corresponding to 10-second sequences for each step of the test, and performs pattern recognition to identify global P onset, QRS onset and offset, and T end. To evaluate the precision and accuracy of the program, since no 12-lead annotated library is available, the authors have collected 30 sequences relative to patients with transmural myocardial infarction at rest, exercise and recovery. The whole set of 12 average cycles for each sequence has been subjected to visual inspection by three independent cardiologists, to identify the reference points for comparison with the program's results. The precision and accuracy of the program have been found to be acceptable.
