Selective and non-selective right bundle pacing for the diagnosis of bundle branch reentry ventricular tachycardia
Authors' conclusion
Right bundle pacing is feasible in patients with BBRVT and may be a helpful manoeuver for the diagnosis of BBRVT.
Study context
- Population
- Patients with infra-nodal conduction disease and bundle branch reentry VT (bundle branch reentry ventricular tachycardia (BBRVT))
- Participants
- 2 patients
- Outcome
- Diagnosis of BBRVT by RB pacing during entrainment
Main finding
As reported in the abstract
- BBRVT diagnosis confirmed in both patients by ventriculo-atrial dissociation and interdependence of conduction system and VT cycle length variations
- Selective and non-selective RB pacing observed in both patients during apical RV pacing for entrainment
- First patient (type A, LBBB morphology): manifest entrainment with non-selective RB capture
- Second patient (type C, RBBB morphology): concealed entrainment by selective RB capture
- Short post-pacing interval at the RB pacing site noted
