There was an interesting article about rapid assessment of chest pain in the ER. If a process like this was implemented there is a potential to avoid unnecessary observations / stress testing. I'll include a link to the Journal Watch Summary and will also include a link to the Journal of the American College of Cardiology. This may be something to bring to the ER doctors' attentions.
