Cardiac pacemaker failure: a complication of trauma

C J Tegtmeyer, D R Bezirdjian, F A Irani

    Southern Medical Journal
    |March 1, 1981
    PubMed
    Summary

    Trauma can damage implanted cardiac pacemakers, leading to malfunction. Prompt recognition of accidental electric shock as a cause of lead fracture is crucial for patient survival.

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Trauma Surgery

    Background:

    • Implanted cardiac pacemakers are vital for managing cardiac arrhythmias.
    • Pacemaker integrity is essential for device function and patient safety.
    • Understanding potential causes of pacemaker malfunction is critical.

    Observation:

    • A case study involving a patient with an implanted pacemaker experiencing lead fracture.
    • The lead fracture occurred subsequent to an accidental electric shock.
    • This highlights a specific mechanism of pacemaker damage due to external trauma.

    Findings:

    • Accidental electric shock can cause significant physical damage to pacemaker leads.
    • Trauma is a critical, yet sometimes overlooked, cause of pacemaker system failure.
    • Fractured leads can lead to complete pacemaker malfunction.

    Implications:

    • Clinicians must consider trauma, including electric shock, in pacemaker malfunction evaluations.
    • Early diagnosis of pacemaker lead fracture is essential for timely intervention.
    • Recognizing trauma as a cause can prevent potentially lethal complications in pacemaker patients.
