Digoxin toxicity: read the rhythm and potassium together

Educational use only. Not clinically reviewed

67-year-old woman for calm electrical, perfusion, electrolyte-risk, antidote-boundary, reassessment, and handoff practice. About 6 simulated minutes.

What you will practise

  • Reconcile product, clock, GI and visual clues, perfusion, rhythm, potassium, and the whole patient.
  • Recognize the life-threatening digoxin pattern without level-, rhythm-, or potassium-only closure.
  • Activate toxicology, resuscitation, cardiac, electrolyte, airway, and safety ownership.
  • Review supplied ECG, level timing, potassium, renal, coingestion, and antidote evidence.
  • Record bounded qualified immune-Fab and rescue intent, then review a strict later report.
  • Hand off recurrent arrhythmia, potassium shift, level interference, renal, rescue, and active risk.
