External Cardiac Pacing at Gertrude's Children's Hospital

Overview

  • What is External Cardiac Pacing?: A non-invasive medical procedure where a device delivers electrical impulses to the heart from outside the body to regulate its rhythm.
  • Why is External Cardiac Pacing used?: To:
    • Temporarily manage abnormal heart rhythms (arrhythmias) until a permanent solution is found
    • Support the heart during a medical procedure or surgery
    • Bridge the gap until a permanent pacemaker is implanted
    • Provide emergency intervention for life-threatening arrhythmias

Detailed Explanation

Step-by-Step Process

  1. Preparation
    • A trained healthcare team from Gertrude’s Children’s Hospital prepares the necessary equipment.
    • The child is positioned comfortably, and the skin is cleaned and prepared.
  2. Electrode Placement
    • Adhesive electrodes are placed on the child’s chest, typically in a anterior-posterior (front-back) configuration.
    • The electrodes are connected to the external pacemaker device.
  3. Device Setup and Programming
    • The healthcare provider sets the pacing mode, rate, and output (electrical impulse strength) based on the child’s specific needs.
    • The device is activated, and the child’s heart rhythm is continuously monitored.
  4. Ongoing Monitoring and Adjustment
    • The child’s heart rhythm, vital signs, and device function are closely monitored.
    • Adjustments to the pacing settings may be made as needed to ensure optimal heart function.

Equipment and Supplies Used

  • External Cardiac Pacemaker Device: Delivers electrical impulses to the heart through the electrodes.
  • Adhesive Electrodes: Transmits the electrical impulses from the device to the heart.
  • Electrocardiogram (ECG) Monitor: Continuously tracks the child’s heart rhythm and adjusts the pacing settings accordingly.
  • Pacing Mode and Parameter Adjustment Tools: Allows the healthcare provider to fine-tune the device settings.

Types of External Cardiac Pacing Modes

  • Demand Pacing (VVI): The pacemaker fires only when the heart’s natural rate falls below a set rate.
  • Asynchronous Pacing (VOO): The pacemaker fires at a fixed rate, regardless of the heart’s natural rhythm.
  • Rate-Responsive Pacing: The pacemaker adjusts its rate based on the child’s physical activity or other parameters.

Potential Risks and Benefits

  • Benefits:
    • Quickly restores a normal heart rhythm in emergency situations
    • Provides temporary support until a permanent solution is found
    • Non-invasive, reducing the risk of surgical complications
  • Risks:
    • Skin irritation or allergic reactions to the electrodes
    • Inappropriate pacing (e.g., too fast or too slow) if not properly adjusted
    • Interference from other electrical devices (e.g., MRI, diathermy)
