Elective: Sam Griffiths – Cardiac Physiology

Optimising the timings of an implanted cardiac device’s (e.g. pacemaker’s) electrical pulse between the top and bottom heart chambers using information from a simple heart scan can improve the health of patients born with structurally normal hearts. There have been no prospective studies indicating whether this is beneficial in adult congenital heart disease (ACHD) patients.

In our study, ACHD patients will undergo device optimisation and a series of tests to evaluate heart function and exercise capacity. The tests will be repeated 8 weeks later to determine the effect of device optimisation on their health. This will indicate whether personalised device optimisation is advantageous in this unique patient group and may inform future clinical care for ACHD patients with devices.
