What is an ECHO?
An Echocardiogram (ECHO) is an image of the heart that is created using ultra-high frequency sound waves that are too high frequency to be heard by the human ear.
The technique is very similar to the ultrasound scanning commonly used in pregnancy and allows the moving heart to be visualised. This can show the size, shape and movement of the heart's valves and chambers as well as the flow of blood through the heart.
These images are then recorded to allow the operator to review them after the test is complete.
Why does the doctor want me to have an ECHO?
An Echo is used to help diagnose certain heart conditions. It will provide information for your doctor regarding the size and shape of your heart, its pumping strength and the location and extent of any damage to its tissues, for example after a heart attack.
It will also tell your doctor if you have a problem with any of your heart valves, by looking at the pattern of blood flow it can help detect the cause of any murmurs heard by the doctor.
What does the test involve?
You will be asked to remove your top items of clothing and once on the examination couch you will be asked lie on your left side, if possible.
An electrocardiogram (ECG) will be recorded during your ECHO and a transducer, which is a small hand-held device at the end of a flexible cable, will be placed against your chest, stomach or neck region with a layer of gel to help the transducer make a good contact.
In order to visualise the images, the room will be darkened. You will hear different sounds during the ECHO as each of the heart valves and movements of blood through the heart are assessed.
How long will the test take?
An ECHO examination generally lasts between 10-30 minutes, depending on the amount of information your doctor requires.
Who will be informed of the results?
The results from your ECHO will be sent to your referring doctor.
Are there any risks or complications involved?
There are no known risks or complications associated with an ECHO.
