Echocardiogram (Echo)

What is an Echocardiogram (Echo)?

An Echocardiogram (Echocardiography or Echo for short) is the term given to an ultrasound examination of your heart. It is a test in which high frequency sound waves are used to create a moving picture of your heart to detect structure and function of the heart.

Why Might I Need an Echocardiogram?

You may be asked to have an Echo for many different reasons. It may be done to measure the size of the chambers of your heart, show how well blood is being pumped through the heart, how efficiently your valves are moving inside your heart, or to check how well your heart is functioning after having a heart attack. An Echo is also able to see any fluid that may have built up surrounding the heart.

What Happens During an Echocardiogram?

A trained and accredited Cardiac Sonographer will perform the test. The sound head (transducer) is a wand that is placed at various positions on your chest. The transducer picks up the echoes of the sound waves and transmits them as electrical impulses. The echocardiography machine then converts these impulses into moving pictures. The different positions around your chest allow the sonographer to examine the entire heart from multiple angles and directions. 

You will be required to be bare chested but will also be given a front opening gown to wear and then lie down on an examination table. ECG electrodes will be placed on your chest and then you will be asked to roll onto your left-hand side. The transducer will be placed on your chest to take the pictures.

Ultrasound gel is used to improve contact and imaging quality. The transducer is applied firmly against the chest wall to obtain the pictures, the Sonographer will ask you if this causes discomfort. The usual positions required are the left side of the chest adjacent to the sternum (breastbone), the area under the left breast, the upper abdomen and the base of the neck. You may hear noises that sound a bit like a washing machine, this represents the magnified ultrasound signal of blood flowing through the heart chambers and valves and is completely normal. The scanning time will be approximately 40 minutes and may vary depending on the findings.

You will at times be asked to take a deep breath in, or to hold a breath out, for a few seconds at time. The Sonographer will guide you through this at the time.

Once finished you will be given a towel to wipe off any gel that you may still have on your chest and to redress. There are showers available at most QCG sites if you require one.
