Hyperkalemia

Hyperkalemia: too much K (K > 5) causing neuro: muscle (weak/paralyze), cardio (slow, irregular, blocks), EKG shows T↑, QT↓, wide QRS if severe, tx w Ca

  • Hyperkalemia
  • too much K (K > 5) causing neuro: muscle (weak/paralyze), cardio (slow, irregular, blocks), EKG shows T↑, QT↓, wide QRS if severe, tx w Ca
  • muscle weakness/paralysis (lower extremities first), palpitations, hx of hyperkalemic periodic paralysis
  • muscle weakness/paralysis, cardio (arrhythmia, blocks/slow hr)
  • K > 5, EKG (T↑, QT↓), severe EKG (sine wave = wide QRS no P), other EKGs (arrhythmias, blocks)
  • cellular K -> plasma: lysis, diabetes, digoxin, b2-block/propranolol. Not peeing out K: low flow renal dz, K-sparing/amiloride, aldosterone--/type4 RTA, anything that messes up renin/AT/aldo (NSAIDs, ACE inh, heparin, spirinolactone, HIV), impaired H excretion (no H to compete with K reabsorption).
  • EKG/neuro (Ca), K -> cell (beta2, insulin+glc, bicarb), K removal (dialysis, resin, diuretic)
  • Na-K (ATPase pump) are opposites. If you pee out Na (aldosterone--, amiloride), then you retain K.
