    Atrial trigeminy, a pacemaker arrhythmia, occurred due to timing issues between the heart

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Electrophysiology

    Background:

    • Pacemaker function relies on precise timing to coordinate heartbeats.
    • DVI pacemaker mode (Dual chamber, Ventricularly inhibited) requires careful programming to avoid arrhythmias.
    • Atrial competition can arise from interactions between intrinsic cardiac rhythms and pacemaker output.

    Observation:

    • A patient with a DVI pacemaker (Byrel-5992) exhibited atrial trigeminy.
    • This arrhythmia stemmed from the coincidence of sinus and atrial escape rates with delayed ventricular sensing.
    • Atrial output stimuli were delivered within the QRS complex, and alternate impulses conducted late to the ventricle.

    Findings:

    • Atrial trigeminy was successfully resolved by reprogramming the pacemaker.

  • Increasing the DVI pacemaker rate eliminated the arrhythmia.
  • Switching the pacemaker mode to VVI (Ventricularly inhibited) also abolished the atrial trigeminy.

    • Implications:

    • Pacemaker reprogramming is a viable strategy for managing pacemaker-induced arrhythmias.
    • Understanding pacemaker-device interactions is crucial for preventing and treating cardiac rhythm disturbances.
    • This case highlights the importance of considering pacemaker settings in the differential diagnosis of arrhythmias.
