Pacemaker catheter-induced systolic murmur

S C Gupta, J T Taguchi

    Angiology
    |April 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Pacemaker insertion can rarely cause heart murmurs. This case describes a musical systolic murmur caused by vibrations from the pacing catheter interacting with heart structures.

    Area of Science:

    • Cardiology
    • Biomedical Engineering

    Background:

    • Cardiac pacing is a common procedure to manage heart rhythm disorders.
    • While extracardiac sounds are known complications, intracardiac murmurs post-pacemaker insertion are infrequent.

    Observation:

    • A patient developed a distinct musical systolic murmur after temporary transvenous endocardial pacemaker placement.
    • The murmur's characteristics suggested an intracardiac origin.

    Findings:

    • The musical systolic murmur was attributed to vibrations generated by the pacing catheter.
    • These vibrations likely occurred due to interaction between the catheter and the tricuspid valve or other intracardiac structures.

    Implications:

    • This case highlights a rare complication of cardiac pacing, emphasizing the need for careful auscultation.
