    DDD pacemakers require optimal atrioventricular synchrony. Interatrial conduction time (IACT) prolongs during right atrial pacing, especially in patients with prolonged P wave duration, necessitating adjustments in pacemaker programming for improved cardiac function.

    Area of Science:

    • Cardiology
    • Electrophysiology
    • Medical Devices

    Background:

    • Atrioventricular synchrony is crucial for systemic hemodynamics, influenced by interatrial conduction time (IACT).
    • DDD pacemakers manage cardiac rhythm by sensing and pacing the right-sided heart chambers.

    Purpose of the Study:

    • To investigate the impact of right atrial pacing on interatrial conduction time (IACT) in patients undergoing DDD pacemaker implantation.
    • To determine optimal atrioventricular (AV) interval programming for DDD pacemakers based on IACT measurements.

    Main Methods:

    • Interatrial conduction time (IACT) was measured using an intraesophageal pill electrode in 25 patients without cardiac medications.
    • IACT was assessed during both sinus rhythm and right atrial pacing at various rates (60-160 bpm).

  • Patients were stratified based on P wave duration (<110 ms and >110 ms).

    • Main Results:

    • Mean IACT significantly prolonged from 95 ms (sinus rhythm) to 122 ms (right atrial pacing) (p < 0.001).
    • Patients with prolonged P wave duration (>110 ms) exhibited longer IACT during both sinus rhythm and right atrial pacing compared to those with normal P wave duration.
    • IACT remained constant across different right atrial pacing rates (60-160 bpm).

    Conclusions:

    • Right atrial pacing prolongs interatrial conduction time (IACT), with a more pronounced effect in patients with pre-existing P wave prolongation.
    • The AV interval during DDD pacing should be programmed approximately 25 ms longer during AV pacing compared to atrial tracking to account for prolonged IACT.
