Pacing and clinical electrophysiology : PACE·2012

A novel pacemaker tachycardia occurred due to T-wave sensing in the atrial channel, triggering ventricular pacing. This "cross-ventricular" endless loop tachycardia can be prevented with proper pacemaker programming.

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Electrophysiology

Background:

  • Conventional dual-chamber pacemakers are used for biventricular pacing.
  • VVIR mode is a common pacing setting.

Observation:

  • An unusual pacemaker tachycardia developed in a patient undergoing biventricular pacing.
  • The atrial channel was connected to the left ventricle, and the ventricular channel to the right ventricle.

Findings:

  • The tachycardia was sustained by T-wave sensing in the "atrial channel," which incorrectly triggered pacing in the "ventricular channel."
  • This resulted in a "cross-ventricular" endless loop tachycardia, a form of reentrant pacemaker tachycardia.

Implications:

  • This phenomenon highlights potential risks with unconventional lead placements in dual-chamber pacemakers.

  • Appropriate pacemaker programming is crucial for preventing such cross-ventricular endless loop tachycardias.
  • Understanding T-wave oversensing is vital for pacemaker safety and efficacy.
