Paediatric ECG

Use the following chart as a quick checklist to review what’s normal and what’s not in a paediatric ECG. 

Remember:

  • Lead V4R in under5’s
  • Manually calculate QTc
  • WPW needs referral for ablation – increase risk of sudden death

If in any doubt discuss with paediatric registrar/senior. If in need of urgent interven:on then contact the paediatric cardiology team in LGI.

1. Placement of Leads: Precordial Leads

In young children, the right ventricle normally extends to the right side of the sternum. To appropriately display right ventricular potentials, ECGs for children in the under five-year age group must include an alternate lead (‘V4R’) on the right side of the chest at a point analogous to the left sided V4.

2. P Waves:

3. Axis:

In utero- high pulmonary pressures and a relatively thick Right Ventricle (RV) -> Initial Right Axis on ECG is normal and resolves after the first 6 months of life

QRS Axis Deviation

  • Chest leads in wrong position

     

RAD:

  • Newborns
  • RVH secondary to Right ventricular outflow tract obstruction eg: Pulmonary
    Stenosis ,Tetralogy Of Fallot, Noonans (characterized by mildly unusual facial features, short stature, heart defects, bleeding problems, skeletal malformations, and many others)
  • RBBB

 

LAD:

  • LBBB
  • LVH secondary to LVOTO (Left Ventricular Outflow Tract Obstruction) e.g. Aortic Stenosis, HOCM

 

Superior Axis

  • AVSD (Atrio ventricular septal defect – Trisomy 21)
4. QTc:

Manually calculate QTc – HERE

Normal QTc:

  • Infants less than 6 months = < 0.49 seconds.
  • Older than 6 months = < 0.44 seconds.

QTc is prolonged in:

  • Hypocalcaemia
  • Myocarditis
  • Long QT syndromes such as Romano-Ward Drugs

QTc is short in:

  • Hypercalcaemia
  • Congenital short QT syndrome
5. Ventricular Hypertrophy

6. T waves:
  • The precordial T-wave configuration changes over time
  • For the first week of life, T waves are upright throughout the precordial leads.
  • After the first week, the T waves become inverted in V1-3 (= the “juvenile T-wave pattern”)
  • This T-wave inversion usually remains until ~ age 8; thereafter the T waves become upright in V1-3.
  • However, the juvenile T-wave pattern can persist into adolescence and early adulthood (= “persistent juvenile T waves”).

Tall, peaked T waves are seen in:

Hyperkalaemia, Dilated LV (volume overload), Benign early repolarisation

 

Flat T waves are seen in:

Normal newborns, Hypothyroidism, Hypokalaemia, Pericarditis, Myocarditis

7. ST Segment:

Some ST changes may be normal:

  • Limb lead ST depression or elevation of up to 1mm (up to 2mm in the left precordial leads).

  • J-point depression: the J point is depressed without sustained ST depression, i.e. upsloping ST depression

  • Benign early repolarisation in adolescents: the ST segment is elevated and concave in leads with an upright T wave.

 

 

Others are pathological:

  • A downward slope of the ST followed by a inverted T.

  • A sustained horizontal ST segment depression

     

 

Pathological ST segment changes are commonly associated with T wave changes and occur in:

  • Pericarditis.

  • Myocardial ischaemia or infarction.

  • Severe ventricular hypertrophy (ventricular strain pattern)

Swallowed Foriegn Body

The ingestion of a foreign body or multiple foreign bodies (FB) is a common presenting complaint in paediatric surgery, with a peak incidence from 12-24 months however, can occur at any age. Ingested foreign bodies rarely cause problems; almost 80% of patients pass the foreign body without intervention – in seven days2 (only 1% require surgical removal). However, occasionally foreign bodies can cause significant morbidity (for example, oesophageal rupture) and 1% require surgical removal.

The presenting symptoms and outcomes of an ingested foreign body is highly dependent on the swallowed object, and for this reason, the guidance for hazardous and non-hazardous foreign body ingestion has been divided accordingly.

Mpox (Formerly: Monkeypox)

Wear Gloves & Wash Your Hands!!!

There have been >100 patients identified as having Mpox in the UK during the current outbreak. Most of these cases have been amongst men who have sex with men.

Reports have suggested that although lesions occur any where including palms and soles. Genital lessons and lymphadenopathy are very common

March 2024 – UKHSA warn there is increasing cases in DRC (Democratic Republic of Congo), so stay vigilant in travellers from central Africa.

DKA – Adult

Things to remember

  • Give 0.9%NaCl
  • Actrapid “Fixed Rate” 0.1unit/kg/hr
  • Basal Insulin e.g. Levemir, Lantus, Semglee, Abasaglar, Toujeo, Tresiba,
    please continue this at usual dose and times
  • Potassium – if below 5.5 will need KCl infusion (see guide)
  • BM <14 – Start 10% Dextrose 125ml/hr
  • BEWARE SGLT-2 inhibitors chance of Euglycaemic DKA

Unsuspected NoF

We have seen multiple incidence where clinicians of ALL grades have assessed patients with falls and examined hips and even mobilised patients

Evidence shows (and reflected in the incidents) this predominantly effects patients with:

  • Communication difficulties: inc. Delirium, dementia, learning difficulties
  • Live in Supported accommodation
  • Normally require help mobilising

If a patient presents with ANY of these and a fall – X-ray Pelvis

 

Neuro-Obs

Neurological Observations MUST include the following:

  • A full set of NEWS2 observations
  • ACVPU assessment (alert, new confusion, voice, pain, unresponsive)
  • GCS (Glasgow coma scale)
  • Pupillary responses
  • Assessment of Limb power

Head Injury – Level 1

Head injury is witnessed, reported, suspected, or cannot be excluded.

  • There is any new onset of neurological symptoms or deterioration.
  • The patient complains of pain / tenderness to the head
  • Extra consideration should be given to patients currently prescribed anticoagulant medication at the time of the fall.

Post fall Neurological Observations must be completed for at least 12 hours and at the above intervals as a minimum:

During this time If there is any deterioration in the patient’s condition including level of consciousness, pupil reaction, limb power, cardiovascular observation you must revert to ½ hourly neurological observation and seek URGENT medical review.

Patients should be reviewed if no change in condition at 12 hours to ascertain if neurological observations are still indicated – this decision must be documented in the medical notes.

Under no circumstances should Neurological observations be omitted because the patient is asleep

Head Injury – Level 2

Admitted with Head Injury

  • With a sudden deterioration in their level of consciousness
  • Who are unconscious on arrival to hospital
  • Post first seizure

During this time If there is any deterioration in the patient’s condition, including level of consciousness, pupil reaction, limb power or cardiovascular observation you must revert to ½ hourly neurological observations and seek URGENT medical review. Patients should be reviewed if no change in condition at 12 hours to ascertain if neurological observations are still indicated – this decision must be documented in the medical notes.

Under no circumstances should Neurological observations be omitted because the patient is asleep.

Intracerebral/Subarachnoid Haemorrhage OR Stroke
  • Acute Primary Intracerebral/Subarachnoid  haemorrhage
  • Any other Ischaemic stroke 
  • Post Thrombolysis /Thrombectomy for Stroke patients only

During this time If there is any deterioration in the patient’s condition, including level of consciousness, pupil reaction, limb power or cardiovascular observation you must seek URGENT medical review and revert to ½ hourly neurological observations as a minimum, or ¼ hourly, if still within the first 2 hours post thrombolysis.

Under no circumstances should Neurological observations be omitted because the patient is asleep.

Major Trauma: STOP>SORT>GO

YAS crews may on occasions (rarely) bring us a Major Trauma patient that meets the criteria for bypass to the MTC because they have a problem that the crew cannot manage, or they won’t survive to LGI e.g. an unmanageable airway/ incompressible haemorrhage. In these instances we will get a pre-alert either from the crew or more likely the Major Trauma Triage Co-ordinator in EOC with some information but primarily the reason the patient is coming to us.
