PALS Narrow QRS Tachycardia Adequate Perfusion Algorithm

PALS Narrow QRS Tachycardia Adequate Perfusion Algorithm

1. Tachycardia is diagnosed by manual testing or heart rate monitor and the child has adequate perfusion – Normal heart rates vary with age/size.

Newborn 0-3 months 80-205 per minute
Infant/Young child 4 months to 2 years 75-190 per minute
Child/School Age 2-10 years 60-140 per minute
Older child/ Adolescent Over 10 years 50-100 per minute

2. Consider possible causes but do not delay treatment

  • Vagal Maneuvers
  • Synchronized Cardioversion
  • Medications
  • Support Airway, Breathing, Circulation

Determine rhythm

  • Sinus tachycardia – Determine cause and treat
  • Supraventricular tachycardia
    • Consider vagal maneuvers
    • Consider adenosine 0.1 mg/kg rapid IV up to 6 mg in first dose
    • May repeat adenosine at 0.2 mg/kg up to 12 mg in 2nd dose
    • Consider amiodarone or procainamide
    • Consider cardioversion at 0.5 to 1 Joule/kg
    • Second cardioversion dose at 2 Joules/kg
    • Consult pediatric cardiologist
    • Continue to search for treatable causes of tachycardia and treat promptly
