College Answer

  • Flattening of P waves & peaked T waves consistent with hyperkalaemia.
  • Treatment of hyperkalaemia:
    • Intravenous calcium based on K levels
    • Bicarbonate
    • Insulin/? Dextrose if she has HONK
    • Resonium / beta 2 agonists
    • Investigate for cause
    • Renal function/electrolytes

Discussion

The referenced article takes good care of the latter. The former is immediately recogniseable and requires little further discussion.

Again, I extend my thanks to LITFL for making public their awesome and massive ECG library.
