ALT Scenario focus: Participants are required to assess and manage a critically unwell infant, recognising SVT as a reversible cause of shock. Management progresses from initial assessment to escalation of treatment while maintaining effective team communication. Learning objectives: Perform a structured A–E assessment and recognise signs of paediatric shock Identify SVT in an infant, including clinical features and ECG interpretation Initiate appropriate vagal manoeuvres (e.g. ice to the face in infants) Escalate safely to adenosine administration if non-pharmacological measures fail Demonstrate effective teamwork, leadership, and closed-loop communication in a time-critical situation Coordinate care while maintaining clear communication with parents
