    External defibrillation can damage permanent pacemakers. Proper paddle placement is crucial to avoid pulse generator malfunction after treating ventricular fibrillation in patients with sick sinus syndrome.

    Area of Science:

    • Cardiology
    • Biomedical Engineering

    Background:

    • Sick sinus syndrome necessitates permanent pacemaker implantation for rate control.
    • Ventricular fibrillation is a life-threatening arrhythmia requiring immediate defibrillation.

    Observation:

    • An 81-year-old female with sick sinus syndrome experienced ventricular fibrillation post-pacemaker implantation.
    • External defibrillation was administered, but paddle placement over the pulse generator caused device failure.

    Findings:

    • External defibrillation can inflict significant damage on implanted pulse generators.
    • Incorrect paddle placement during defibrillation can lead to complete pacemaker dysfunction.

    Implications:

    • Standardized defibrillation protocols must emphasize avoiding direct paddle contact with implanted electronic devices.
