Your visit

Outpatient visits

When attending your outpatient appointment, you will be seen by a consultant on most occasions, but sometimes by a clinical fellow in training who will discuss any management plan with the supervising consultant.

Most often, an echocardiogram is performed on the day, but if you live near the hospital you may be called for the echo prior.

A specialist nurse is present in all clinics and they will be there to help you understand your heart condition and or answer any queries you might have after you’ve seen the doctor.

Inpatient stays

If you require admission, you will reviewed and admitted under the on-call GUCH consultant cardiologist and seen daily by one of the GUCH team.
