CASE #1: A 50yo woman with no past medical history is eating at a Mexican restaurant and developed abdominal pain. She reports that the pain started suddenly and traveled up into her chest. She briefly lost vision in her right eye. The pain traveled back down into her stomach and then resolved. Her vision came back as well. The whole episode lasted less than 15 minutes and by the time she arrives at the free-standing ED, she is completely symptom-free.
