Hyperkalemia

"What are the main ECG pointers for hyperkalemia?
  • Though it is good to know the classic ECG progression of hyperkalemia, do not be fooled by a normal or nonspecific ECG in hyperkalemia.
    • The relationship between serum potassium and ECG manifestation is not cut and dry as we are taught. Don’t get into a false sense of security…treat the patient in front of you!
    • Keep hyperkalemia in the differential diagnosis for a patient with an ECG showing a very wide QRS complex
  • Keep in mind the differential of a “peaked” T-wave:
    • Hyperkalemia
    • Hyperacute T-waves from ischemia
    • De Winter’s T-waves
    • Benign Early Repolarization
  • Hyperkalemia is a great mimicker – think about it in your STEMI-mimics, bradyarrhythmias, tachyarrhythmias, AV blocks, etc., especially if the ECG is not adding up on your interpretation."
