I think Judge Nicklin summed up what he felt were the main messages in the articles we complained about. the presentation of these articles, as a whole, reinforced this message. We won on almost all points. Well, maybe.

Many systems now refrain from showing computer "normal" ECGs to the busy emergency physicians at triage because of very poorly conceived articles that say that if the computer algorithm says "normal," the emergency physician should not be bothered. We have shown many examples of this on this blog. No further follow up is available.
