During the test you will be lying down on your left side.
First You will be connected to an ECG machine that records the electrical activity of the heart and monitors the heart during the procedure using small, adhesive electrodes. The ECG tracings that record the electrical activity of the heart will be compared with the images displayed on the echocardiogram monitor.
The room will be darkened so that the images on the echo monitor can be seen by the sonographer (ultrasound tech).
A special gel will be placed on the front of your chest and then the sonographer will take a special probe and move it around your chest area, applying varying amounts of pressure to get images of different locations and structures of your heart. This will make a picture of your heart that can be seen on a monitor.
After the procedure, the technologist will wipe the gel from your chest and remove the ECG electrode pads. You may then put on your clothes.
