The PALS Wide QRS Tachycardia Algorithm addresses critical pediatric cardiac conditions. It provides a systematic approach for healthcare providers to manage pediatric emergencies and ensure adequate perfusion in pediatric patients.

PALS (Pediatric Advanced Life Support) wide QRS tachycardia perfusion algorithm provides the ultimate guideline for effective intervention that stands critical in pediatric resuscitation situations.

Particularly when a child is suffering from rapid heart rate with a widened QRS complex detected in an ECG (Electrocardiogram). This condition is often presented with adequate perfusion.

Sequential Explanation of the Flow chart

  1. For wide QRS complex tachycardia: QRS duration >120 ms
  2. Check regularity & irregularity
    • Determine if QRS is identical to SR(Sinus Rhythm)
  3. If Yes 
    • Consider SNT (Supraventricular Tachycardia) and BBB (Bundle Branch Block)
  4. If No
    • Consider Atrial Fibrillation (Atrial flutter/AT with variable conduction)
  5. Discover other underlying causes
    • Can include electrolyte imbalance, structural heart disease, medication toxicity)
  6. Attempt Vagal Maneuver
    • Apply firm pressure on the child’s eye
    • Massage the carotid sinus
  7. Put patient on Adenosine
    • 0.1mg/kg rapid IV-6mg (1st Dose)
    • 0.2mg/kg -12mg (2nd Dose)
  8. AED/Cardioversion
    • 0.5-1 joule/kg
    • 2 joules/kg (2nd Dose)

Key Findings of PALS Wide QRS Tachycardia Adequate Perfusion Algorithm

  1. Assessment of Clinical Condition: Evaluate for a palpable pulse and signs of adequate perfusion.
  2. Identify Underlying Cause: Determine potential causes like electrolyte imbalances or structural heart disease.
  3. Attempt Vagal Maneuvers: Perform maneuvers if safe, such as carotid sinus massage or Valsalva maneuver.
  4. Consider Adenosine: Administer adenosine if wide QRS tachycardia is regular and vagal maneuvers fail.
  5. Monitor for Stability: Consult pediatric cardiology if the child remains stable with adequate perfusion.
  6. Continuous Monitoring: Continuously monitor vital signs and clinical status, prepared for advanced interventions if necessary.
