What to Expect


How to Prepare

There is no special preparation for an ECG.

Checking In

When you arrive at the Diagnostic Test Centre, check in at the reception desk. The receptionist will ask you for:

  • ​Health Card (OHIP Card). If you do not have an OHIP card, please bring another form of government-issued photo ID (such as a driver’s license, passport, or other provincial health card). Please arrive 15 minutes before your appointment.
  • Your name, address and birth date

Before the ECG

After you check in with the receptionist, you will have a seat in the waiting room. The technician will call you when it is time for your test and take you into the room.

When you have finished changing, a technologist will take you into the room. They will explain the procedure and ask for your consent.

During and After the ECG

The technician will ask you to disrobe from the waist up and place the ECG electrodes on your chest. You will then be attached some wires and be asked to lie still for a few minutes while ECG machine records the electrical activity of your heart.

The Results of Your ECG

Once the test is completed, technician will give you a copy your ECG to take back to your physician. Your doctor can review it and discuss the results with you directly.

How Long Will Your Appointment Be?

An ECG usually takes approximately 20 minutes.
