Brief summary

This study examines the difference between implanting a conventional pacemaker and a novel technique in pacemaker implantation where the pacing lead is implanted in the His-bundle and deep septal region of the heart. This novel technique could circumvent the known adverse effects of conventional pacemakers, and result in improved patient outcomes. Conduction system pacemaker is hypothesised to result in improved cardiac function compared to conventional pacemakers.

Interventions

Patients in the interventional arm will undergo implantation of pacemaker using the 3830 lead to capture the conduction system instead of conventional 5076 lead in the right ventricle, via standard of care venous (subclavian or axillary) access. This procedure will be performed by electrophysiologist, and is a once off procedure (not recurring). This procedure will be performed in fully-functional cardiac catheterisation laboratory, where pacemakers are routinely inserted. The procedure takes ap

Patients in the interventional arm will undergo implantation of pacemaker using the 3830 lead to capture the conduction system instead of conventional 5076 lead in the right ventricle, via standard of care venous (subclavian or axillary) access. This procedure will be performed by electrophysiologist, and is a once off procedure (not recurring). This procedure will be performed in fully-functional cardiac catheterisation laboratory, where pacemakers are routinely inserted. The procedure takes approximately 30 minutes. The implanted pacemakers are permanent systems (lifelong), however depending on clinical circumstances an upgrade to biventricular pacemaker may be performed if a clinical indication is met.
