Before an echocardiogram, a technician will attach small plastic adhesive patches (electrodes) to your child's chest to monitor the heart’s rhythm.
The technician will place gel on your child's chest and then place a small camera, called a transducer, on the gel. Your child will feel a slight pressure as the technician moves the transducer around his or her chest to get pictures of the heart. Once the echocardiogram is done, the technician will wipe the gel from your child's chest and remove the electrodes.
To get clear pictures, it’s important for children to be as still as possible during the procedure. In some cases, younger children may need to be sedated for the echocardiogram.
