Auto-interference by a demand pacemaker

J S Geddes

    European Journal of Cardiology
    |January 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Pacemaker malfunction occurred due to exposed battery connections, causing inappropriate inhibition and intermittent fixed-rate pacing. This interference highlights the importance of proper device sealing and lead integrity in pacemaker function.

    Area of Science:

    • Cardiovascular Medicine
    • Biomedical Engineering
    • Medical Device Technology

    Background:

    • Pacemakers are crucial for managing cardiac arrhythmias.
    • Unipolar demand pacemakers require careful implantation to ensure proper function and sensing.

    Observation:

    • Inappropriate pacemaker inhibition and ECG baseline instability were noted immediately post-implantation.
    • Higher frequency artifact and intermittent fixed-rate pacing indicated severe sensing interference.

    Findings:

    • The observed pacemaker malfunctions stemmed from an exposed connection on the pacemaker's surface.
    • This exposed connection linked the negative battery terminal to the electronic components, causing interference.

    Implications:

    Related Experiment Videos

    • Device integrity and proper sealing are critical for preventing pacemaker malfunction.
    • This case underscores the need for rigorous quality control in pacemaker manufacturing and implantation procedures.
