Chapter 10 Objectives Describe the benefits of acquiring a 15-lead ECG Describe the proper lead placement for Leads V4R, V8, and V9 Describe the hemodynamic problems associated with a right ventricular infarction List 3 clinical signs of RVI On a 15-lead ECG, recognize ECG changes for a posterior and right ventricular MI 109

Upper Saddle River, NJ Acquiring a 15-Lead (V8, V9) Posterior leads V8: 5th IC space midscapular line V9 goes between V8 and the spine Place Lead V5 wire on V8 and V6 wire on V9 Acquire the second 12- lead Re-label the new leads

Upper Saddle River, NJ Right Ventricular Infarction RV gets blood supply from the RCA Up to 50% of inferior MI will have RVI Preload problems Use nitrates with extreme caution Fluid bolus of perhaps 1 liter or more is indicated
