Echocardiography is the study of heart and function using sound waves (ultrasound).

2D Suface Studies

This is done by moving an ultrasound transducer to various locations on your chest, back or abdomen in order to image each structure of the heart from various viewpoints. An echocardiogram can provide a wealth of helpful information, including the size and shape of the heart, pumping capacity, and the location and extent of any tissue damage.

To book a 2D surface study, please call:

Georgetown Hospital:                                    905-873-0111 ext. 8236
Milton District Hospital:                                 905-878-2383 ext. 7704
Oakville Trafalgar Memorial Hospital:       905-338-4686

3D Transesophageal Echocardiography (TEE)

Transesophageal Echos are ultrasound images of the heart obtained by inserting a 3D probe into the esophagus. This procedure allows the Cardiologist to see the heart from a different viewpoint internally.

TEE studies are conducted at OTMH only.  To book test, please call:  905-338-4686.

Exercise Stress Testing

A stress echocardiogram allows doctors to see how your heart looks and performs when it is under the stress of exercise.  Exercise stress echo studies are performed at OTMH only.  To book test, please call:  905-338-4686.

Dobutamine Stress Echocardiography

A dobutamine stress echo is an alternative to an exercise stress echo when patients are unable to perform the physical activity of pedaling. A drug called dobutamine is injected to mimic the effect of exercise on the heart. 

Dobutamine stress echos are performed at OTMH only.  To book test, please call:  905-338-4686.


Preparing For Your Procedure

2D Echo and Colourflow Doppler

  • No preparation
  • Children between the ages of 1- 3 years may require sedation

Transesophageal Echo

  • Nothing to eat or drink from 10:00 p.m. the night before the test. An Echo technician will phone and confirm  this with you
  • Make arrangements for someone to drive you home after the test, as sedation will be given
  • Bring a list of your current medications.


Ordering Criteria

The Cardiac Care Network offers an Echocardiography Quality Improvement Program (EQI) that  provides guidelines related to all aspects of the echocardiography facility, from the background and training of the medical and technical staff, to requirements for the type of equipment used, to minimum standards for Quality Improvement (QI) to guidelines outlining testing appropriateness.

Please find a list of common indications and appropriateness criteria for echocardiography below.
