Peri-arrest tachyarrhythmia (RCUK adult algorithm)

A source-linked educational visual of adult peri-arrest tachyarrhythmia instability, cardioversion and rhythm-directed management from RCUK guidance.

Interactive clinical algorithm

This source-backed visual algorithm is available in the interactive page experience. Open the original guidance and the node notes before clinical use.

How to read this visual

  • Read across the columns for the phases of the pathway; the swimlanes are who acts — Resuscitation team, Rhythm and defibrillation, Expert cardiology input.
  • Bold marks the dose, threshold or time limit that decides the next step; the rest of a label is context.
  • Identify life-threatening features before attempting rhythm classification.
  • Open notes for cardioversion, drug options and pre-excitation/polymorphic-VT cautions.

Clinical notes

  • Treat sinus tachycardia by treating its cause, not by applying this antiarrhythmic pathway.
  • Use senior/cardiology support and local drug/sedation protocols.
