    Pacemaker after-potential oversensing can cause pacing rate changes. Adjusting stimulus pulse duration or width non-invasively resolved this issue in VVI patients.

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Electrophysiology

    Background:

    • Non-competitive pacing can lead to complications like oversensing and recycling.
    • Pacemaker stimulus after-potentials are a known cause of these complications, often mimicking T-wave sensing.

    Observation:

    • Two cases of after-potential oversensing in patients with R-wave inhibited (VVI) pacemakers are presented.
    • The oversensing caused recycling of the pulse generators, leading to a slowed pacing rate in both instances.

    Findings:

    • Decreasing the duration or width of the pacemaker's stimulus pulse was found to be an effective non-invasive solution.
    • This adjustment reduced the magnitude of the after-potential signal, thereby eliminating oversensing.

    Implications:
