February 2009 CE Site Code #107200E-1209 Revisions to the CMC EMS System CE Program and Determining ST Elevation on 12-Lead EKG s Prepared by: Bill Glade, DC, Wauconda Fire Department Sharon Hopkins, RN, BSN, EMS Educator
Date of CE presentation: February 2009 Topic: Overview of the Revised Condell EMS System CE and Determining ST Elevation on 12 lead EKG s Behavioral Objectives: Upon successful completion of this module, the EMS provider will be able to: 1. Identify the changes in the Condell EMS System CE program as taught in class. 2. Identify the appropriate components of the cardiac conduction system with the correct wave form on a rhythm strip. 3. Identify when it is appropriate to obtain a 12 lead EKG. 4. Identify the criteria for significant ST elevation following guidelines reviewed in class. 5. Identify EKG leads that view the anterior, inferior, lateral walls, and septum. 6. Recognize the patterns of an MI after viewing the components of a 12 lead EKG. 7. Identify typical and atypical presentations of an acute MI. 8. Identify complications associated with an inferior wall MI. 9. Identify complications associated with an anterior/septal wall MI. 10. Identify complications associated with a lateral wall MI. 11. Identify interventions for the complications of heart block, pulmonary edema, and cardiogenic shock. 12. Identify the SOP guidelines for the patient presenting with acute coronary syndrome as written in the Region X SOP s. 13. State dosing and precautions for Aspirin, Nitroglycerin, and Morphine. 14. Identify ED staff expectations of EMS personnel when calling the hospital to report a patient with ST elevation identified on a 12 lead EKG. 15. Identify EMS expectations when delivering a patient to a hospital after ST elevation has been identified on a 12 lead EKG. 16. Actively participate in 12 lead EKG scenario practice and discussion. 17.Given a picture, trace the order of the cardiac conduction system correctly. 18. Given a manikin, correctly place electrode placement to obtain a 12 lead EKG. References: Aehlert, B. EKG s Made Easy third Edition. Elsevier Mosby. 2006. Beasley, B.
