Pacemaker-mediated tachycardias: an unresolved problem.

J W Harthorne, A C Eisenhauer, D M Steinhaus

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

    Dual chamber pacemakers restore heart rhythm but can cause pacemaker-mediated tachycardias. Judicious programming of these devices can minimize the incidence and rate of these tachycardias, improving patient outcomes.

    Area of Science:

    • Cardiology
    • Biomedical Engineering

    Background:

    • Dual chamber pacing systems offer significant advancements in cardiac rhythm management by restoring atrioventricular synchrony and enabling rate variability.
    • These systems, however, are susceptible to pacemaker-mediated tachycardias (PMTs).

    Purpose of the Study:

    • To describe the mechanisms and clinical implications of pacemaker-mediated tachycardias in dual chamber pacing.
    • To highlight the role of programming in managing PMTs.

    Main Methods:

    • Review of pacemaker function and potential causes of retrograde conduction.
    • Analysis of factors influencing PMT rates and clinical consequences.

    Main Results:

    • Pacemaker-mediated tachycardias can be triggered by various factors including retrograde P-waves and electromagnetic interference.
    • The rate of PMTs is dictated by the pacemaker's programmed upper tracking rate.
    • PMTs can lead to myocardial ischemia in patients with coronary artery disease.

    Conclusions:

    • Pacemaker-mediated tachycardias are a known complication of dual chamber pacing systems.
    • Careful and judicious programming of pacemaker settings is crucial for minimizing the occurrence and severity of PMTs.
