Outcome Measures

Primary Outcomes (2)

  • Proportion of patients in which left-bundle branch pacing is achieved at implantation

    Defined as a paced (pseudo) right bundle branch block QRS morphology with terminal r/R' in lead V1 and any of the following: i) recording of a LBB potential during intrinsic rhythm (only in patients with normal ventricular activation), ii) transition from non-selective to selective LBBP or non-selective LBBP to LV myocardial capture during decreasing pacing output, iii) abrupt shortening of stimulus to R wave peak time in V6 ECG lead (V6RWPT) ≥10 ms during implantation, iv) V6RWPT \< 75ms or \< 80ms in patients with preexisting left bundle branch block or v) an interpeak interval (V1RWPT - V6RWPT) ≥ 33ms.

    Baseline (During implantation)

  • Proportion of patients with left-bundle branch pacing criteria at 24 hours

    Defined as a paced (pseudo) right bundle branch block QRS morphology with terminal r/R' in lead V1 and any of the following: i) recording of a LBB potential during intrinsic rhythm (only in patients with normal ventricular activation), ii) transition from non-selective to selective LBBP or non-selective LBBP to LV myocardial capture during decreasing pacing output, iii) abrupt shortening of stimulus to R wave peak time in V6 ECG lead (V6RWPT) ≥10 ms during implantation, iv) V6RWPT \< 75ms or \< 80ms in patients with preexisting left bundle branch block or v) an interpeak interval (V1RWPT - V6RWPT) ≥ 33ms.

    At 24 hours (before discharge)

Secondary Outcomes (1)

    At 24 hours

Study Arms (2)

Lumenless lead

ACTIVE COMPARATOR

Left bundle branch stimulation using leads without internal lumen (Lumenless; Medtronic Selectsecure 3830, Minneapolis, USA).

Device: Pacemaker implantation with conduction system pacing using Lumenless leads

Stylet-driven lead

ACTIVE COMPARATOR

Left bundle branch pacing using leads with internal lumen and retractable helix (Tendril STS 2088TC, Abbott, Inc., USA; Solia S60, Biotronik, SE \& Co., KG, Germany; Ingevity +, Boston Scientific, Marlborough, MA, USA).

Device: Pacemaker implantation with conduction system pacing using Stylet-driven leads

Interventions

Pacemaker implantation for conduction system pacing will be done using leads without internal lumen (Lumenless; Medtronic Selectsecure 3830, Minneapolis, USA).
