Read the first 7 Bradycardia With a Pulse flashcards as text

  1. A 4-year-old has a heart rate of 68 bpm with poor perfusion. After ensuring airway and oxygenation, what is the next intervention if the child remains symptomatic?

    Answer: Give epinephrine 0.01 mg/kg IV/IO

    If bradycardia with poor perfusion persists despite adequate oxygenation, epinephrine is the drug of choice in PALS.

  2. Which ECG finding is most commonly associated with symptomatic bradycardia in pediatric patients requiring PALS intervention?

    Answer: Complete (third-degree) heart block

    Complete (third-degree) heart block causes complete dissociation between atria and ventricles, producing severe bradycardia requiring intervention.

  3. A 7-year-old with known congenital heart disease presents with HR 48 bpm, altered consciousness, and hypotension. Oxygen has been applied. What should be done NEXT?

    Answer: Administer atropine 0.02 mg/kg IV

    Atropine is the first-line drug for symptomatic bradycardia with a pulse when the rhythm is vagally mediated or AV block is suspected.

  4. What is the minimum single dose of atropine recommended in PALS to avoid paradoxical bradycardia?

    Answer: 0.02 mg/kg with a minimum of 0.1 mg

    PALS recommends atropine 0.02 mg/kg with a minimum single dose of 0.1 mg to avoid paradoxical bradycardia from very small doses.

  5. During management of a bradycardic infant, the team achieves IV access. Atropine has been given twice without improvement. What is the next pharmacologic step?

    Answer: Administer epinephrine infusion

    If atropine fails to correct symptomatic bradycardia, epinephrine infusion (0.01–1 mcg/kg/min) is the next pharmacologic agent in PALS.

  6. A 6-year-old is bradycardic with a HR of 42 bpm and is unresponsive. A rhythm check shows sinus bradycardia. CPR is in progress. Which statement about CPR in this scenario is correct?

    Answer: CPR should be initiated when bradycardia causes hemodynamic compromise despite interventions

    PALS guidelines state CPR should be started for bradycardia causing cardiopulmonary compromise that is unresponsive to initial interventions.

  7. Which of the following conditions is a reversible cause of bradycardia that should be specifically addressed in pediatric patients?

    Answer: Hypothermia

    Hypothermia is a reversible H cause of bradycardia; rewarming the patient can restore normal heart rate.
