    Cardiology Clinic

    The Cardiology Clinic offers the following services to pediatric patients with various heart conditions:

    ECG Testing
    This is a simple test that records your child’s heartbeats.  Thirteen stickers are applied to your child's chest, arms and legs.  Leads (insulated wires), which are connected to a machine with a screen, are then connected to each sticker.  This test can take a minimum of 5 minutes if your child is relaxed, cooperates and stays still for the time needed.

    Echocardiogram (Echo)
    This is an examination of the heart by ultrasound.  There is no radiation or risk involved in the procedure.  It is used to detect structural and functional abnormalities, enlargement or inflammation of the heart, and other conditions. The test takes approximately 45 minutes.

    Holter Monitor
    This is a 24 hour recording of your child’s heartbeats, which is useful for assessing suspected abnormalities of the heart rhythm.  Three stickers are applied to your child’s chest and connected to a recorder about the size of a deck of playing cards.  Your child cannot take a bath or shower while the recorder is on, but otherwise should engage in normal daily activities.

    Exercise (Stress) Test
    An exercise test allows us to evaluate the response of your child’s heart to exercise.  For this test, your child will need running shoes, loose clothing and a bottle of water.  Your child is connected to 10 ECG stickers and a blood pressure cuff will be applied on one arm to monitor blood pressure.  Your child will start off with a slow walk on the treadmill and then gradually increase the pace to running for as long as they can.  After running, a cool down recovery period is observed. The test will take approximately 45 minutes.

    What to Expect

    Two-day clinics are held in January, March, June, and October and are led by:

    Dr. Gilbert Gross, Cardiologist, SickKids
    Dr. Jennifer Russell, Cardiologist, SickKids
    Karen Jocko, Diagnostic Cardiac Sonographer

    Each appointment lasts approximately 1.5 hours.  The cardiologist will complete an ECG test, and may send you for an echocardiogram or exercise (stress) test.

    Please bring a list of medications with you and do not use body lotion the day of your appointment.

    Patients are usually scheduled for follow-up at the time of the visit.  Families will receive clinic scheduling information by phone and/or by mail 1-2 months before their scheduled appointment.


    We accept referrals from a Pediatrician or Cardiologist.  Referrals can be made through the EpiCare system of SickKids Hospital in Toronto. Please specify that you would like the patient seen in Sudbury on your referral.
