Requesting and preparing for your appointment
To make an appointment with a cardiologist, your pediatrician, family physician or another physician-specialist must refer you. All referrals are reviewed and appointments are scheduled based on the urgency of the case.
If this is an urgent referral requiring an assessment in less than 48 hours, the referring physician must call CHEO’s main number (613-737-7600) and page the Cardiologist on service.

How does the referral process work? |
The referring physician provides information about the patient to the Cardiology Department. This information is then reviewed and used to decide the appropriate time to be seen by a Cardiologist. Because of this, the Division of Cardiology cannot guarantee an appointment within a specific period of time. Patients are notified directly either by phone or by mail of their appointment time. If no one is at home at the time of the call, a message is left to call the Cardiology Department to confirm the appointment.
Cardiology will contact the referring physician if there are special instructions for the family and patient regarding their visit. |

About your appointment
What should I bring for my clinic appointment? |
NOTE: If your child requires antibiotics prior to procedures i.e dental surgery because of his or her heart problem, the cardiologist or the nurse will inform you. Written information is given to you, which reviews indications for antibiotic use. The dentist or family physician prescribes the antibiotics for your child. |
What can my child bring from home? |
A bottle or soother is helpful for an infant. We do offer video or DVD movies as a distraction in the reception area and for echocardiogram testing only. We encourage you to bring along a favorite toy, blanket, storybook or movie to help your child remain relaxed. |
What to bring to my exercise test? |
Bring shorts/jogging pants, running shoes and a bottle of water with you.
Do not have a heavy meal within 2 hours before the test but do have a snack 1 hour before e.g.: soup, juice, fruit or granola bar. |
Cardiology clinics and programs
Pediatric Cardiology clinic |
A visit to the clinic will begin with an initial assessment by one of the cardiology nurses. Because CHEO is a teaching hospital affiliated with the University of Ottawa Faculty of Medicine, your visit may also include an initial assessment by a senior medical student or pediatric resident (a doctor who is doing special training to become a pediatric doctor) prior to seeing the cardiologist. Depending upon what tests are required, your visit may take up to two hours. Most new patients will not require any testing on their initial visit. |
Arrhythmia clinic |
In the CHEO Arrhythmia Clinic, we care for children and youth who have problems with their heart rhythm (or heart beat). We also care for children who are at risk for heart rhythm problems. Some of these problems run in families, so we use the specific expertise to carefully assess children and teenagers to see if they also have the condition. |
Pacemaker clinic |
The Pacemaker Clinic is scheduled several times a month for routine follow-up. Previously seen patients and their families can call the Nursing Line (613-737-7600 ext. 3109) with questions concerning the child’s pacemaker or other health issues.
When your child’s heart needs a pacemaker, it is inserted to relieve symptoms of heart rhythm disturbances. It does this by restoring normal heart rates. Regular follow-up clinic visits ensure the pacemaker is working properly.
During your child’s visit, a small computer is used to read information inside the pacemaker. The first step is to apply 5 stickers attached to 5 leads (insulated wires), which connect with the small computer. Then, a special pacemaker magnet is placed on the skin over your child’s pacemaker. Many parts of the pacemaker are checked during these visits including the pacemaker settings, the battery status and the leads.
Many of the pacemaker’s functions can be adjusted or programmed by the pacemaker doctor or nurse to meet your child’s needs and to help the system last as long as possible.
During this appointment you may also be scheduled for an ECG and/or Holter. X–rays are also routinely requested at this time. |
Satellite and outreach clinics |
The Cardiology Department performs outreach clinics to Iqualuit, Baffin Island once to twice a year. Children with suspected and known heart disease from the communities of Nunavut can receive full cardiac evaluations during these clinics, often saving them a more extensive trip to Ottawa. |
Fearless physical activity |
The Canadian Congenital Heart Alliance is proud to present the Fearless Physical Activity event series to Ontarians living with congenital heart disease. Fearless Physical Activity is designed to provide you and your family the opportunity to try fun physical activities available in your local community. Each season, multiple Fearless Physical Activity events will be held across the province. Come learn about fun ways to integrate physical activity into your lifestyle! |
Maple Minds |
Maple Minds is a mindfulness, yoga and relaxation group program to help manage chronic disease. Learn more about our Maple Minds Program and how it can help your family. |
Summer Camp |
The 2019 summer camp approved for cardiac kids, running from August 12th to August 16th, is a great opportunity for kids with various cardiac conditions to have fun, experience camp life, meet new friends, and make wonderful memories, all while in a safe environment. This 1-week day camp will be filled with activities such as canoeing, climbing wall, swimming, high ropes course, crafts and outdoor group activities, all adaptable according to the child’s health. An open-door day, for the whole family, will take place on May 26th, 2019. You’ll be able to learn more about the opportunity as well as meet other families. For more information and/or to register, please contact Angelica Blais by email at ablais@cheo.on.ca. |

Frequently asked questions
What if my child suffers from palpitations? |
||||||||
Palpitations or the sensation of rapid or forceful heartbeat is a common symptom in children. If the episodes are brief and go away on their own they generally do not require treatment. It should be noted that children can obtain very fast heart rates with exercise or excitement. The sensation of rapid heart rate that comes on progressively with exercise and gradually settles at rest is likely normal. Rapid heartbeat associated with fainting is a concern. | ||||||||
Questions about heart murmurs |
||||||||
|
||||||||
What are chest pains? |
||||||||
Chronic, recurrent chest pain in children is rarely related to the heart. Most chest pain in children comes from the chest muscles or the small joints between the ribs. Chest pain that occurs at rest and with exercise is generally benign. Pain that is described as “sharp” or “stabbing” is also less of a concern particularly if it is made worse by a deep breath. Pain occurring in association with meals may be caused by a common condition called gastroesophageal reflux, the result of stomach acid coming back up the swallowing tube. | ||||||||
What should I know about bacterial endocarditis? |
||||||||
Bacterial endocarditis is an infection of the inside lining of the heart or the heart valves. It is a serious but rare complication in some children with heart defects. It may occur after certain procedures, such as dental work. For cardiac patients with certain types of heart defects, a preventative dose (1 dose) of antibiotics may be prescribed prior to the procedure to decrease the chance of such an infection. Your cardiologist will be able to discuss with you whether your child requires this type of antibiotic treatment. | ||||||||
How do I access CHEO cardiac satellite clinics? |
||||||||
Normally the satellite clinics are organized for specific times in coordination with the regional hospital. Once families are referred, they have the option of seeing the cardiologist in Baffin Island, or seeing the cardiologist in Ottawa at CHEO. | ||||||||
As a patients, where can I direct my questions? |
||||||||
New patients who have been referred to a cardiologist at CHEO but have not yet been seen will need to call their family physician if they have questions about their child’s health. Until a cardiologist sees your child, your family physician or pediatrician remains the most knowledgeable about your child’s health. That is different once the child has seen a cardiologist.
For patients previously seen at the Clinic, inquiries can be directed to the Nursing Line at 613-737-7600, ext. 3109. |
||||||||
What will happen during our cardiac clinic visit? |
||||||||
Your appointment may last between two and three hours. During your clinic visit, we will:
If your child or teen has tests during this visit, your cardiologist will discuss the results with you before |
||||||||
How can I renew a prescription? |
||||||||
Don’t forget to ask for prescription renewals at your appointment. | ||||||||
What can I expect from electrophysiology testing? |
||||||||
We perform these tests:
These tests are performed to assess your child’s heart’s electrical system or activity and are used to diagnose abnormal heartbeats or arrhythmia. Stickers will be applied to the skin, the technicians performing the test have different ways to remove stickers as pain free as possible. |
||||||||
What is your policy on taking photos in the clinic? |
||||||||
Please ask about our hospital policy before taking pictures in the clinic.It is not permitted to take pictures of testing. Written consent is required to take pictures of staff. |
Cardiology testing
Electrophysiology |
||||||||||
This is a simple investigation that measures the electrical activity of the heart. A variety of electrophysiology testing performed at CHEO includes:
|
||||||||||
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. Generally, children between 3 months and 3 years of age require sedation in order to lie still for the procedure. A variety of specialized studies performed at CHEO includes:
|
||||||||||
Cardiac catheterization (Cath) |
||||||||||
Cardiac Catherization is a specialized procedure used to look inside your child's heart with the use of a special X-ray machine. This procedure is generally performed with anesthesia.
Catherizations are performed upon the request of your cardiologist. Prior to the procedure, your child will be seen in the pre-assessment unit and meet with the interventional cardiologist. Cases are booked according to urgency as determined by the cardiology team. Diagnostic (investigative) and interventional cardiac catheterization procedures are conducted at CHEO:
