If we took this as the gold standard, we would conclude that the computer interpretation was safe and accurate at least accurate enough to not miss STEMI, and that physicians should not be interrupted to interpret it, because there would be no change in patient management. What is the gold standard for ECG interpretation: patient outcome!!!
