    Replace current med with?
    • Tall peaked T-waves: =Hyperkalemia...depol and incr resting potential  l/t peaked T-waves and wide QRS
    • Furosemide: Tx of HTN, and K-sparring
    • Replace with: Calcium gluconate (stabilizes myocardium for long enough to decr K-level)

  27. Acute LBBB
    Tx: same as STEMI ==> Cardiac Catheterization
  28. Livedo reticularis
    S/E: of card cath. Embolization of released cholesterol in subQ tissues
  29. Cardiac Catheterization
    • Indications: acute MI and unstable angina refract to medical intervention
    • Fxn: meas blood flow / pressures in heart chambers and vessels
    • S/E: Livedo reticularis - skin becomes mottled and discolored d/t ischemia
  30. Beta-bl O/D Tx
    Tx: Glucagon
  31. Split S2
    • Physiologic: AoV closes before PulmV (incr with Inhl)
    • Pathologic: (Wide / Fixed / Paradoxical)
    • Wide: Pulm Stenosis or RBBB (path: d/t amnt time for RV to eject blood --> delay pulmV closing)
    • Fixed: A/w Atrial Septal Defect (same amnt of blood shunted through ea beat)
    • Paradoxical: AoS, or LBBB (PulmV closes before AoV)
  32. LVH Causes:
    • Chronic exposure to:
    • Pressure overload state: AoS or Chr-HTN (*MCC of LVH = HTN)
    • Volume overload state: AoR or MR, and Dilated Cardiomyopathy (DCM)
  33. 2 causes of Pressure overload state
    Aortic Stenosis and Chronic Hypertension
  34. ECG of LVH
    Sokolov-Lyon Criteria: Depth of S-wave in V1 + tallest R-wave height in V5-6 must be >35mm
  35. Tx of HTN in LVH
