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.

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
Administration: Titrate to patient response
Transcutaneous Pacing
Procedure: Apply pacing pads and begin pacing at the lowest effective energy level.
Monitoring: Observe patient comfort and adjust settings as necessary
