Double ventricular pacing in a patient with a "DDD" universal pacemaker.

A W Nathan, A J Camm

    Pacing and Clinical Electrophysiology : PACE
    |May 1, 1984
    PubMed
    Summary

    A pacemaker lead dislodged, causing breathing problems. Replacing the atrial lead fixed the dual-chamber pacing (DDD) function, resolving symptoms.

    Area of Science:

    • Cardiology
    • Biomedical Engineering

    Background:

    • Dual-chamber pacemakers (DDD) are crucial for managing bradyarrhythmias.
    • Pacemaker lead integrity is essential for optimal device function.

    Observation:

    • A patient with a DDD pacemaker presented with dyspnea and abnormal electrocardiogram (ECG) findings.
    • ECG revealed pacing artifacts and altered QRS morphology.
    • X-ray confirmed atrial lead displacement into the ventricle due to active fixation helix retraction.

    Findings:

    • Late lead dislodgement caused suboptimal DDD pacing.
    • The retracted active fixation helix was identified as the cause of lead displacement.
    • Resolution of symptoms and restoration of normal DDD pacing occurred after atrial lead replacement.

    Implications:

    • Highlights the importance of lead stability in DDD pacing.
    • Underscores the potential for lead dislodgement due to active fixation helix issues.
    • Emphasizes the need for vigilant monitoring and timely intervention for pacemaker lead complications.
