Glasgow Emergency Paediatric ECG Guideline (GEPEG)

exp date isn't null, but text field is


This guidance document is to support RHC ED staff in utilisation of the ECG electronic reporting capacity and subsequent manual interpretation of the ECG.

This document also describes the patient disposition pathway options for children where an ECG has been performed.

ECG recording

Name, date of birth and CHI MUST be entered on ECG machine to gain appropriate paediatric ECG analysis for electronic report.

Once the ECG has been performed, the ECG machine provides an electronic report at the top of ECG.  A quick manual checklist should be performed by the ED physician. (See below).



  • Whist lying down / supine or sitting
  • On swimming
  • On exercise
  • Family history of sudden unexplained death
  • Family history of epilepsy

Prolonged QTc

  • Syncope with QTc > 450ms
  • Otherwise QTc > 460ms in both boys and girls

Patients presenting with ANY of the above ‘RED FLAGS’ MUST have an ECG and their case discussed with cardiology PRIOR to discharge even if ECG appears normal (includes out of hours).

Consideration will be given to whether a 24 hour ECG / Holter monitor or exercise tolerance test will be required – on discussion with Cardiology team.

ECG interpretation

‘Normal’ electronic report

If the electronic report is normal and the manual checklist is acceptable, no cardiology follow-up is necessary

‘Abnormal’ electronic report

If the electronic report is abnormal, manual checklist should be applied and detailed analysis of abnormality should take place.  If the ED physician is confident, that on manually checking, the ECG is normal, no cardiology follow-up is required

Abnormality identified on manual checklist

If any abnormalities are identified on the manual checklist, then the ECG should be uploaded to clinical portal and ED discharge summary sent for e-vetting.

If in doubt upload ECG to clinical portal, send discharge summary for e-vetting, or if significant concerns, discuss with on call cardiology registrar.

Manual checklist for Paediatric ECGs

ECG vetting procedure

If patient fulfils above criteria for e-vetting then ED staff to complete the ‘pink’ ED referral letter circling Cardiology and write “for e-vetting” next to this. 

Please ensure the manual interpretation findings of the ECG are documented within the ED clinical notes with the indication for e-vetting noted.

This should go to the ED reception with the ED notes that will be scanned with a copy of the ECG and the onward referral to cardiology will be made by the ED secretaries via medical records.

The scanned ED card and ECG will be ‘e-vetted’ by the cardiology team when they receive the referral made by the ED secretaries as per the above referral process.
