Summary

This is a pilot study into the effects on heart function when pacing the right ventricle (RV). This study aims to enrol a population who are clinically indicated to receive a pacemaker.

When normal conduction within the heart fails, the treatment may be to implant a permanent pacemaker. Pacing involves passing a lead via a vein to the heart and using an electrical impulse to stimulate a beat.

Increasingly the available evidence suggests that long term RV pacing is associated with complications - left ventricule (LV) dysfunction, heart failure, atrial fibrillation (AF) and death in some patients. What we do not see are a large proportion of all patients who receive pacemakers suffering pacing related adverse effects.

If there could be a way of identifying those patients in the group who go on to develop pacing induced cardiomyopathy at the time of initial pacing implant, this would be a very valuable clinical measure. These patients could be identified from the outset and paced with a biventricular device to avoid the pacing induced cardiomyopathy. Whilst much energy has been directed towards the LV as a focus of the clinical markers of disease, little has been published looking at RV haemodynamics.

We plan to study a cohort of patients who are clinically indicated to receive a pacemaker and study their RV in detail at the time of implantation. We will use conductance catheters and echocardiography to determine measures of pumping function. We will then follow them up for a period of six month using echocardiography and blood markers of heart dysfunction. In those patients who have a reduction in heart function we will then look for common patterns within their initial measurements.
