Bradycardia Management

Bradycardia Management Opener

This module describes the emergent management of bradycardia, where the patient has a palpable pulse.


  1. Bradycardia with a palpable pulse

The management of bradycardia requires monitoring, administration of medication, and possibly transcutaneous pacing. Ensure that you explain your findings and decisions to the patient as you go along. Some patients may be haemodynamically unstable and unable to understand; communicate with family members if present. See Transcutaneous Pacing for specific patient information.


Bradycardia management may be an emergency procedure. Always:

  1. Know where defibrillators, transcutaneous pads, and red trolleys are kept. Know the relevant staff and keep your seniors’ contact details close at hand.
  2. Familiarise yourself with the defibrillators in your work area. Check that they are maintained regularly and have pads and the correct connections.
  3. Keep unstable patients in resuscitation bays with continuous monitoring.

The patient should be lying flat on their back on a firm surface. There should be space behind the head of the bed for staff to stand to give rescue breaths if the patient deteriorates.


Follow medical asepsis with non-sterile gloves.

  1. Hello

    1. Tap the patient’s shoulder and call hello. Look for a response.
    2. Feel and listen for breathing with your ear close to the patient’s mouth. Look for chest rise. Don’t take more than 10 seconds.
    3. Feel for a carotid pulse. Don’t take more than 10 seconds. Identify bradycardia.
  2. Airway: open and maintain as indicated.

  3. Breathing: administer oxygen/ventilation as indicated.

  4. Circulation: attach BP cuff and cardiac monitoring. Determine if the patient is stable or

    . Obtain a 12-lead ECG as soon as possible.

  5. Consider and correct

    (Hs and Ts).

  6. Unstable adult:

  7. Unstable child with heart rate under 60/minute: start CPR if unresponsive. Administer adrenaline first, then try atropine.

    . Consider transcutaneous pacing.

  8. Stable patient: no emergency intervention. Refer to cardiology.


I am unfamiliar with or unsure about transcutaneous pacing.

Call a senior for assistance. Refer to Transcutaneous Pacing for guidance.
