There were several important findings in this study: 1) the comparative 3-lead “abc” system performed similarly to the comparative 12-lead ECG in detecting coronary artery occlusion, achieving over 90% sensitivity, specificity, and accuracy in determining coronary occlusion; 2) spot measurements demonstrated much poorer performance compared to comparative ones where a left anterior descending artery occlusion conferred a better performance as compared to the circumflex artery, although did not reach statistical significance.
