Summary

Dual chamber pacemakers with automatic mode switching are recommended for symptomatic bradyarrhythmic atrial fibrillation. Preventive pacing strategies are under investigation to reduce atrial fibrillation recurrence, with septal pacing showing promise.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Devices

Context:

  • Symptomatic bradyarrhythmic atrial fibrillation necessitates pacing therapy.
  • Dual chamber pacemakers should include automatic mode switching for atrial fibrillation.
  • Mode switching prevents rapid ventricular pacing during atrial tachyarrhythmias and optimizes dual chamber pacing during sinus rhythm.

Purpose:

  • To review the established role of pacing in symptomatic bradyarrhythmic atrial fibrillation.
  • To discuss the benefits of automatic mode switching in dual chamber pacemakers.
  • To explore emerging preventive pacing strategies for atrial fibrillation recurrence.

Summary:

  • Pacing therapy is standard for symptomatic bradyarrhythmic atrial fibrillation, with dual chamber devices featuring automatic mode switching recommended.

  • Automatic mode switching prevents rapid ventricular pacing and allows beneficial dual chamber pacing during sinus rhythm.
  • Preventive pacing, including septal pacing and specific algorithms, is being investigated for reducing atrial fibrillation recurrence, though further trials are crucial.

    • Impact:

    • Optimized pacemaker function in atrial fibrillation patients, improving hemodynamics and reducing thromboembolic events.
    • Potential for novel pacing strategies to decrease the burden of atrial fibrillation.
    • Clinical practice may incorporate septal lead placement and preventive pacing for select patients with recurrent atrial fibrillation.
