Left Bundle Branch Area Pacing
Conditions
Brief summary
Evaluation of ventricular arrhythmias sensing via a left bundle branch area pacing lead.
Interventions
DEVICELeft bundle branch area pacing
A dual-chamber DF-1 defibrillator is implanted. Left bundle branch area pacing is performed for cardiac resynchronization therapy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients with successful defibrillation at 35 Joules. | 24 hours | After manual induction of ventricular fibrillation, a 35 Joules will be delivered with the implanted defibrillator. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time from ventricular fibrillation induction to defibrillation shock. | 24 hours | After manual induction of ventricular fibrillation, the duration of appropriate ventricular sensing will be measured until the 35 Joules shock is delivered. |
| Number of appropriate and inappropriate arrhythmic episodes. | 6 months | The occurrence of appropriately or inappropriately detected episodes with a high ventricular rate ≥170 beats-per-minute will be recorded. |
