    This study introduces a screw-in atrial lead and intraoperative mapping to improve atrial pacing. The method achieved stable P wave amplitude and low stimulation thresholds, enhancing safety and long-term performance.

    Area of Science:

    • Cardiology
    • Biomedical Engineering
    • Medical Devices

    Background:

    • High atrial stimulation thresholds and unstable P wave amplitude are significant challenges in atrial pacing.
    • Existing atrial pacing methods often face limitations in electrical performance and long-term stability.

    Purpose of the Study:

    • To evaluate the efficacy of a novel screw-in atrial lead combined with intraoperative atrial mapping for improving atrial pacing parameters.
    • To assess the acute electrical performance and long-term safety of this combined approach.

    Main Methods:

    • A screw-in atrial lead was implanted in 16 patients.
    • Intraoperative atrial mapping was performed to identify optimal lead placement for electrical performance.
    • Acute stimulation thresholds and P wave amplitudes were measured.

  • Patients were followed for up to 28 months to assess lead stability and complications.

    • Main Results:

    • The screw-in atrial lead demonstrated an average acute stimulation threshold of 0.49 +/- 0.18 Volt at a 1 ms pulse duration.
    • The average acute peak-to-peak P wave amplitude was 4.6 mV +/- 1.3.
    • No complications such as dislocation or bleeding were observed during the follow-up period.
    • The combined approach achieved atrial strength-duration relationships comparable to ventricular pacing.

    Conclusions:

    • Intraoperative atrial mapping is crucial for optimizing lead placement and enhancing atrial pacing safety margins.
    • The screw-in atrial lead, when used with mapping, offers a promising solution for improving long-term atrial pacing performance.
    • This technique contributes to achieving stable and effective atrial pacing, addressing current clinical concerns.
