Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim is to provide evidence of the long-term benefits of personalised pacemaker programming on heart function and battery longevity.

This will be achieved by showing in a single centre, phase II, double-blind, randomised, placebo-controlled trial that reducing the amount of pacemaker beats to a minimum reverses these changes and extends battery life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients (n=70) with long-term (\>2 years) permanent pacemakers with avoidable RV pacing will be invited to participate in a single-centre, phase II, randomised, double-blind placebo-controlled trial of optimised pacing programming versus standard care. Those randomised to the intervention arm will have personalised programming to avoid right ventricular pacing, whilst those allocated to standard care will have no programming changes made. All participants will be invited back at 6 months for a repeat echocardiogram, quality of life assessment (EQ-5D-5L), blood tests and pacemaker check.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Usual Care

Patients received echocardiogram but no pacemaker reprogramming or personalisation.

Group Type NO_INTERVENTION

No interventions assigned to this group

Personalised programming

Patient will have tailored pacemaker programming based on echocardiographic findings, blood results, and symptoms in an attempt to minimise right ventricular pacing and extend battery longevity.

Group Type ACTIVE_COMPARATOR

Personalised programming

Intervention Type DEVICE

Reprogramming protocol already test in an observation cohort will be utilised which will direct physiologists to consider pacemaker mode, base rate, utilisation of rate response, hysteresis, sleep and rest rates as well as lead outputs.
