Anteroseptal MI Complications

  • Look at V2-V4,5
  • CHF/Cardiogenic shock
    • Large area of myocardium involved
  • Bradycardia
    • Bundles thru septum knocked out leading to wide complex
  • Myocardial tissue rupture

Inferior MI Complications

  • Look at II, III, aVF
  • Bradycardias and AV block
    • Increased vagal tone
    • Sinus Node supplied by RCA in 60% of patients
    • AV node supplied by RCA in 90% of patients
  • Papillary muscle rupture
    • RCA supplies inferior septum
    • MI + new murmur + CHF think valve injury

Right Ventricle MI Complications

  • Inf MI with ST elev III>II, ST elev V1>V2, ST dep V2
    • Lead III and V1 looks most at R side of heart
  • RV mostly supplied by RCA
  • Hypotension most severe complication
    • Volume load
    • AVOID vasodilators, do not give SLNG


  • LV Free Wall Rupture
    • 5-14 days after MI, earlier in thrombolysis pts
    • Leaking of fluid outside can cause tamponade
      • Look for JVD, pulsus paradoxus, diminished sounds
    • Emergent Echo if stable
    • Give IVF and consult CV surgery for pericardiocentesis and thoractomy
  • Septum rupture
    • Blood fills RV
    • Reduce afterload and consult CV surgery
    • Consider IABP
    • consult CV surger
  • Papillary muscle rupture
    • Reduce afterloadconsult CV surgery
