An Echocardiogram (echo) is an ultrasound study used to evaluate cardiac structure and function.
The test is performed by a cardiac technician using a probe and jelly on the chest wall to obtain images, which are subsequently interpreted by a Consultant Cardiologist.

It is not necessary to be admitted to hospital for this procedure. An Echocardiogram will take about 30 minutes.
The result of the test is then sent to your Consultant.
