Pocket guide: ECG interpretation guide and pattern library

Written by Dr Joanna Woodnutt BVM BVS MRCVS | 3 September 2026

Build assurance in your ECG interpretation with our practical pocket guide. From distinguishing normal sinus rhythms to recognising potentially life-threatening arrhythmias, confidence comes from having a clear, structured approach and the right reference materials at hand.

Combining a structured interpretation framework with a comprehensive visual pattern library, the guide helps you match ECG findings to common rhythms, QRS morphologies, and their underlying pathophysiology.

The guide provides a valuable reference for identifying both normal and abnormal patterns, helping to bridge the gap between obtaining an ECG and making sense of the results. It also includes clear guidance on ECG setup, lead placement, troubleshooting artefacts, and recording high-quality traces to ensure reliable results.

Whether you're reviewing an ECG in general practice, monitoring an anaesthesia patient, or investigating an arrhythmia, this guide offers practical support that can be applied in everyday clinical settings.

Inside the guide:

  • A step-by-step approach to ECG interpretation
  • A visual pattern library of common cardiac rhythms and arrhythmias
  • The pathophysiology behind key ECG findings
  • Heart rate assessment and rhythm analysis
  • ECG setup, patient preparation, and lead placement
  • Troubleshooting tips for obtaining clear, diagnostic-quality traces
  • Guidance on recognising and interpreting common artefacts
