Adult Bradycardia with Pulse Algorithm

Understanding and effectively applying the ACLS bradycardia algorithm is essential for health care professionals managing patients with symptomatic bradycardia with a pulse. Prompt recognition and intervention can prevent the progression to more severe cardiac events. This guide provides an overview of the key aspects of the ACLS bradycardia algorithm, incorporating critical dosing details to enhance your ability to respond effectively during emergencies.

Importance of the ACLS Bradycardia Algorithm

The ACLS bradycardia algorithm is a systematic approach designed to assist clinicians in:

• Accurate Assessment: Determining the severity of the patient’s bradycardia with pulse and its impact on hemodynamic stability.
• Identifying Underlying Causes: Recognizing reversible factors contributing to the bradycardia.
• Appropriate Intervention: Implementing treatments based on the patient’s condition, including specific medication dosages and pacing when necessary.

By adhering to the ACLS bradycardia algorithm, health care providers can improve patient outcomes and reduce the risk of deterioration to cardiac arrest.

Adult Bradycardia with Pulse Algorithm

Key Steps of the ACLS Bradycardia Algorithm

1. Assess and Monitor the Patient

• Airway and Breathing: Ensure the airway is open and the patient is breathing adequately; provide oxygen if needed.
• Circulation: Monitor blood pressure, heart rate, and oxygen saturation.
• Vital Signs: Obtain a complete set of vital signs, including level of consciousness.
• Establish IV Access: Prepare for medication administration.
• 12-Lead ECG: obtain an ECG and identify the type of bradycardia.

2. Evaluate for Signs of Poor Perfusion

• Symptoms of Unstable Bradycardia with Pulse:
  • Hypotension
  • Altered mental status
  • Signs of shock
  • Chest pain
  • Acute heart failure

3. Identify and Treat Underlying Causes

Consider possible contributing factors to bradycardia (remember the H’s and T’s):

• Hypoxia
• Hypothermia
• Hypovolemia
• Hyper/Hypokalemia
• Toxins
• Tamponade (cardiac)
• Tension pneumothorax
• Thrombosis (coronary or pulmonary)

4. Implement Appropriate Interventions

If the Patient is Symptomatic (Unstable Bradycardia with Pulse)

First-line Medication: Atropine

• Atropine IV Dose:
  • First Dose: 0.5 mg bolus
  • Repeat: Every 3-5 minutes as needed
  • Maximum Total Dose: 3 mg

If Atropine is Ineffective

Proceed to one of the following:

• Transcutaneous Pacing
• Dopamine Infusion
• Dopamine IV Infusion Dose:
  • 2-20 mcg/kg per minute
  • Titrate to patient response
  • Taper slowly as needed

Epinephrine Infusion

• Epinephrine IV Infusion Dose:
  • 2-10 mcg per minute
  • Titrate to patient response

5. Consider Expert Consultation

If the patient does not respond to initial treatments or if the management plan is uncertain, seek expert consultation.

6. Prepare for Transvenous Pacing

If the patient remains unstable despite medications and transcutaneous pacing, prepare for transvenous pacing.

Doses and Details

Atropine IV Dose

• Initial Dose: 0.5 mg IV bolus
• Repeat: Every 3-5 minutes as needed
• Maximum Total Dose: 3 mg

Dopamine IV Infusion

• Dose Range: 2-20 mcg/kg per minute
• Administration: Titrate to patient response; taper slowly

Epinephrine IV Infusion

• Dose Range: 2-10 mcg per minute

Transcutaneous Pacing

• Procedure: Apply pacing pads and begin pacing at the lowest effective energy level.
• Monitoring: Observe patient comfort and adjust settings as necessary
