Cardiology clinic

The cardiology clinic is a non-invasive pediatric cardiology service that provides testing and medical care for children and youth with concerns effecting their heart.

Some children have congenital heart disease (birth problems with the heart), while other children develop heart conditions (heart conditions that are not present at birth but develop in childhood.)

What we do

The cardiology clinic assesses and treats medical concerns of the heart including, but not limited to:

  • congenital heart disease,
  • heart murmur,
  • irregular heartbeat,
  • poor growth,
  • poor exercise capacity, and
  • high blood pressure.

The services our pediatric cardiology program provides include:

  • Initial assessment and follow-up appointment through clinics.
  • Electrocardiography (ECG) testing.
  • Echocardiography (ultrasound of the heart)
  • Cardiac and pulmonary exercise tests (a test that measures the heart’s rate and rhythm during exercise.)
  • Fetal assessment in coordination with the maternal fetal assessment unit.

Cardiac care may begin prior to birth, in the case of babies whose heart condition can be detected by prenatal ultrasound, and continues until the age of 18, at which time patients are transitioned to adult health-care services.

Who we see

We provide care for children and youth up to their 18th birthday.

Frequently asked questions

What is a cardiologist?

A cardiologist is a physician who specializes in the cardiovascular system (your heart and body vessels).

What can I except when my child visits the cardiology clinic?

Appointments for new patients take 60 to 90 minutes and could be up to two hours, depending on how much testing your child requires and the urgency of the situation.

Most patients will have an electrocardiogram, which is a 5-10 minute procedure that requires placing stickers on your child’s chest and limbs to measure the heart’s electrical activity.

Other testing is based on medical need and may include:

  • an ultrasound (also known as an echocardiogram) to check the structure and strength of the heart;
  • a Holter monitor, which is a 24-hour rhythm assessment; or
  • a stress test, which involves walking and running on a treadmill.
