About the Division of Cardiology
The Division of Cardiology provides a complete range of diagnostic, consultation and treatment services. A cardiology consultation is a chance for you to be seen by a specialist in cardiology, who has the expertise and training to evaluate your condition and identify any potential concerns. The cardiologist will ask questions about medical history, physical activity and other information that will help provide an assessment. If further tests are needed, your cardiologist will request these. Learn more about the services and support we offer below.
To make an appointment with a cardiologist, your physician must refer you. All referrals are reviewed, and appointments are scheduled based on the urgency of the case.
If this is an urgent referral needed 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 to discuss the referral.
Cardiology clinics and programs
| Pediatric Cardiology clinic |
| A clinic visit starts with an 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 assessment by a senior medical student or pediatric resident (a doctor who is doing special training to become a pediatric doctor) before seeing the cardiologist. Depending on what tests are needed, your visit may take two to three hours. |
| Arrhythmia clinic |
| In the CHEO Arrhythmia Clinic, we care for children and youth who have problems with their heart rhythm (or heartbeat). We also care for children who are at risk for heart rhythm problems. Some of these problems run in families, so we use specific expertise to carefully assess children and teenagers to see if they also have the condition. |
| Pacemaker clinic |
| The Pacemaker Clinic is scheduled monthly for routine follow-up. Previously seen patients and their families can call the Cardiology Medline (613-737-7600 ext. 3109) with questions about the child’s pacemaker or other health issues. A pacemaker is needed in some cases of heart rhythm differences. A pacemaker works to restore 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 five stickers attached to five 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 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. |
| Satellite and outreach clinics |
| Twice a year, the Cardiology Department performs outreach clinics to Iqaluit, Nunavut. Children with suspected and known heart disease from Nunavut can receive full cardiac evaluations during these clinics, often saving them a trip to Ottawa. |
| Fetal Cardiology Clinic |
| Our Fetal CardiologyClinicperforms detailed ultrasound evaluation, counseling and treatment for heart problems in the developing baby during pregnancy. Most types of major congenital heart defects can be diagnosed after 18 weeks of pregnancy. Referral to this clinic is made by obstetrical or other providers when an at-risk fetus is identified. |
About our team
The Department of Cardiology is made up of seven full time pediatric cardiologists, one nurse practitioner and a team of health care professionals. Our team includes a social worker, cardiac technologists, nurses, echosonographers, patient service clerks, a genetic counsellor and administrative support.
Information for children, youth and families
| Before your appointment |
| What should I bring for my clinic appointment?
Note: If your child needs antibiotics before dental procedures because of their heart problem, the cardiologist or the nurse will tell you. The dentist or family physician prescribes the antibiotics for your child. Please sign up for a MyChart account before your first visit. Our scheduling team will call you to schedule an appointment. If something changes and you need to reschedule your appointment, please let us know at least 24-48 hours in advance by calling 613-737-7600 x3091. No-shows or frequent cancellations may result in discharge from the service. |
| What to expect during your appointment |
| Your appointment may last up to two to three hours. During your clinic visit, we will:
What can my child bring from home? A bottle or soother is helpful for an infant. We do offer TV programming in the waiting room and as entertainment during echocardiogram testing. We encourage you to bring along a favourite toy, blanket, storybook or movie to help your child remain relaxed. What to bring to my exercise test? Bring shorts or jogging pants, running shoes and a bottle of water with you. Do not have a heavy meal within two hours before the test but do have a snack one hour before such as soup, juice, fruit or granola bar. |
Frequently asked questions
| What is a heart murmur? |
||||||||
| A murmur is an extra sound made as the blood flows through the heart. Most murmurs in children are from normal blood flow innocent murmurs. These murmurs are very common, happening in over half of all children. Most innocent murmurs disappear as your child grows. Some murmurs can indicate a problem with blood flow. This can be determined by assessing the specific sound of the murmur. Your child or teen may need some tests such as an electrocardiogram (ECG) or echocardiogram to investigate the murmur depending on how it sounds. |
||||||||
| What causes chest pain in children and teens? |
||||||||
| Chest pain in children is rarely related to the heart. Most chest pain in children comes from the chest muscles or the small joints in the rib cage. This type of pain often happens during rest, is often described as “sharp” or “stabbing” and is often made worse by taking a deep breath. Pain that happens during meals may be caused by a common condition called gastroesophageal reflux, the result of stomach acid coming back up the swallowing tube. The description of the chest pain can usually pinpoint the cause. Sometimes cardiac testing may be needed to investigate chest pain. |
||||||||
| 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 of antibiotics will be given before the procedure to decrease the chance of such an infection. Your cardiologist will discuss with you whether your child needs this type of antibiotic treatment. |
||||||||
| How do I access CHEO cardiac satellite clinics in Nunavut? |
||||||||
| Referrals for patients in Nunavut will be directed to the twice-yearly clinics in Iqaluit by the referring provider. Urgent referrals may need to be seen in Ottawa depending on the timing of the Outreach clinics. |
||||||||
| As a patient, 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 is the most knowledgeable about your child’s health. Once your child has seen a CHEO cardiologist, questions about their heart care can be directed to the Cardiology Clinic Medline at 613-737-7600, ext. 3109. |
||||||||
| How can I renew a prescription? |
||||||||
| Don’t forget to ask for prescription renewals at your appointment. Your pharmacist can also request a renewal directly with the clinic. Please note that some medications or conditions will require an in-person assessment prior to providing a renewal. |
||||||||
| What type of testing is done in the Cardiology clinic? |
||||||||
|
|
||||||||
| 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. |

How does the referral process work?
The referring physician provides information about the patient to the Cardiology Division. This information is then reviewed to decide the right timeframe 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 told directly by phone or 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.
Please note that some referrals may be forwarded to our pediatric cardiology community partners in Ottawa and Gatineau instead of being seen at CHEO.
Referral criteria for specialized testing
Some cardiology testing can be requested without a cardiologist physician referral.
ECG’s may be requested without a consultation. Echocardiograms can be requested for certain conditions without a cardiology consultation (for example hypertension monitoring, some genetic conditions, chemotherapy monitoring). Please note that echocardiography has a limited role in the evaluation of chest pain, murmurs, syncope and palpitations in children and teens, and most requests for echocardiography without consultation will be declined for these conditions.

| Cardiac catheterization |
||||||||||
| Cardiac Catheterization is a specialized procedure used to look inside your child's heart with the use of a special X-ray machine. This procedure is done with general anesthesia. Catheterizations are done with the request of your cardiologist. Before 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 decided by the cardiology team. Diagnostic (investigative) and interventional cardiac catheterization procedures are done at CHEO. Diagnostic catheterizations are done to learn more and/or diagnose your child’s heart condition. It also helps the cardiologist to decide the best treatment for your child. Interventional catheterizations are performed to fix heart malformations. Many defects can now be fixed by the implantation of a device, stent or coil using interventional catheterization procedures. |
