A guide for parents
Having an echocardiogram
Before, during and after
Follow your own hospital team’s instructions about medicines and eating or drinking; these can be different for each child.
- Before
- Ask whether your child needs any preparation or help to stay still.
- During
- A probe and gel make ultrasound pictures of the heart.
- After
- Staff wipe off the gel. Ask when the team will discuss the results.
01
Moving pictures

An echocardiogram, or echo, uses ultrasound to examine the heart. It shows the parts of the heart, how well it pumps and how blood moves through it. Echo and ECG sound similar, but they answer different questions. The specialist looks at the pictures alongside your child’s condition and earlier scan results. An echo may be repeated over time to see whether things change.
02
What happens next
At the appointment
For a usual chest scan, staff put gel on the skin. They move a small handheld scanner, called a probe, over it. Your child may need to change position and stay reasonably still. Some young children need sedation, medicine that helps them relax or become sleepy. This helps staff get clear pictures. Not every echo needs sedation.
The hospital will tell you if sedation is planned and give preparation instructions. A fetal echo is a specialist heart ultrasound for a baby during pregnancy.
Helping your child feel involved
Ask whether a familiar toy, video or comfort item can be used. Let staff know if your child needs an explanation before being touched, extra time or communication support. If sedation is planned, use the hospital’s current instructions rather than advice from another family. Ask who will explain the results. The person taking the pictures may need a specialist to explain the full diagnosis.
Write down any new terminology so it can be clarified before you leave.
03
Questions to ask
Save the questions you want to take to your next appointment. You can edit them in your Journal.
- Will our child need sedation for the scan, and what preparation or support will they need if so?
- What can this scan tell you about our child’s heart, and are there questions it cannot answer?
- Who will explain the results, including any changes from the previous scan and what they mean for our child?
