Mark was working with a Spanish speaking patient who was complaining of chest pain and abdominal pain. Initial EKG was within normal limits. Mark was at the patient's bedside assessing the patient when he noticed the patient had a slight change in his cardiac rhythm on the bedside cardiac monitor. Mark notified the ER physician immediately and a repeat EKG was done. The second EKG showed the patient was having an acute STEMI. The ED physician was very impressed that Mark was able to see such a slight change to the patient ST segment on the monitor; to know the patient was having a STEMI would not have been discovered so quickly and may have caused a delay in getting him to the Cath Lab. Mark demonstrates why our ER is simply better! Who else can diagnose a STEMI by noticing an elevation change that was >4mm on a monitor?!
