Echocardiography

An echocardiogram uses ultrasound to create images of the heart and help clinicians assess its structure and function.

About this examination

How echocardiography works

A probe sends sound waves into the body and receives echoes that are used to create images of the heart. This is different from an ECG, which records the heart’s electrical activity rather than making ultrasound images.

The type of echo can vary

There are different types of echocardiogram, and instructions can depend on the type requested. The clinician determines which examination is appropriate. Ask the centre to confirm the exact type available before arranging your appointment.

Before you visit

Contact the centre to confirm current availability, referral requirements, the type of echocardiogram requested and any preparation instructions.

What does an echocardiogram show?

An echocardiogram uses ultrasound to create images of the heart so a clinician can assess its structure and how it is working.

What happens during a standard echocardiogram?

For a common chest-based scan, sticky patches may monitor your heart rate while gel and an ultrasound probe are used on your chest. Other types of echocardiogram follow different steps.

Do I need to prepare for an echocardiogram?

Preparation depends on the type. Many chest-based scans need no special preparation, while a more detailed scan may require you to stop eating and drinking beforehand. Follow the instructions provided for your examination.
