Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

You must have
NOTHING to eat or drink from midnight the night before your test. Medications can be taken with a sip of water unless your doctor tells you not to.
A friend or family member is required to be present in the lab during the test. You will be sedated during this procedure. The friend or family member will be instructed on how to care for you after the exam and be required to drive and/or accompany you home. They can also help you gather information, take notes and ask questions.
Bring with you to your appointment your:
When you arrive at the
Echocardiography Labcheck in at the reception desk. The receptionist will ask you:
You will be given a name band to wear. You will be given a brief list of questions to answer regarding your medical history and medications.
A sonographer will escort you to a change room where you will be asked to remove all clothing from the waist up off. A patient gown will be provided. Please leave your valuables with the person who has come with you for the test. You will be taken into the procedure room.
During the test, the sonographer may perform a transthoracic echocardiogram. The anesthesia assistant will review your medical history with you and determine whether you need a sedative during the test. The cardiologist will then explain the procedure and its risks – feel free to ask questions before you sign the consent form.
Monitors will be attached to you to record your heart rate, heart rhythm, blood pressure and blood oxygen level during the test. A needle will be inserted into an arm vein to give you medications to help you relax. Then you'll be given a small amount of oxygen. You'll also be asked to remove any dentures.
A local anesthetic (Xylocaine) will be sprayed to the back of your throat to numb it, and you'll be given a liquid form of Xylocaine to gargle. Then we'll need you to lie on your left side. The doctor will slowly pass the probe through your mouth and into the esophagus. You may feel some pressure and discomfort as the probe is being directed into position, but it's generally not painful. Once the probe is in position, the doctor will take pictures of your heart. The sonographer will assist in operating the ultrasound machine.
After the test, you'll stay in the lab until you recover from the sedative. The anesthesia assistant will review with you the instructions for after your test, and you'll get a written copy of them before you go home.
Your throat will still be frozen/numb so you should have nothing to eat or drink for at least 2 hours afterwards. Then you should start by slowly taking sips of liquid. Make sure that you feel the liquid going down your throat properly. If you don't feel the liquid, wait half an hour and try again.
Do not drive or operate heavy machinery for the remainder of the day. Arrange in advance for someone take you home.
The report will be sent to the doctor who requested the TEE and he/she will discuss the results with you at a later time.
A transesophageal echocardiogram (TEE) usually takes 2 to 3 hours.
We do everything that we can to stay on time. Unfortunately, your appointment may be delayed by unforeseen circumstances. We recommend that you come prepared for delays.
