Virtual Care

PACE is please to offer Virtual Care / Telemedicine appointments. Telemedicine uses telecommunications technology to provide clinical health care in Ontario at a distance. These appointments are for patients who have difficulties with transportation, live far away, or just need a quick follow up. For more information or to set up an telemedicine appointment with a PACE cardiologist, please call 1-888-662-0680.

Electrocardiography (ECG)

An electrocardiography test (ECG or an EKG) records the electrical activity of your heart and can detect rhythm associated with heart disease. It is completed by placing stickers (called electrodes) on the patient’s chest, which can then record the electrical activity that occurs as the heart beats.

Exercise Stress Testing

An exercise stress test, sometimes also known as a treadmill test, or stress test, allows us to monitor how your heart responds to exercise on our specialized medical treadmill. Stickers are placed on the chest to capture your heart rhythm. The incline of the treadmill and speed will slowly increase in short intervals as a cardiac technologist monitors the electrical activity of your heart as you walk and run on the treadmill. The test will be completed when you reach your target heart rate, or sooner in the event that you tell the technologist that you wish to stop.


An echocardiogram (ECHO) uses ultrasound to capture images of your heart while it beats. This is the same non-invasive ultrasound technology used to check the health of a baby during pregnancy. An echocardiogram is used to assess the anatomical function of your heart; valves, chambers, size and shape of the heart, pumping capacity, how the heart relaxes, blood flow in the heart (Eg. leaky valves) location and extent of cardiac disease.

Stress Echocardiography

A stress echocardiography test, or sometimes known as a stress echo, is a combination of a stress test along with an echocardiogram of your heart. It’s a procedure that determines how well your heart and blood vessels are working. In a stress echocardiogram, ultrasound images of your heart are taken before and immediately after you walk on a treadmill. Stress echocardiography is non-invasive.

24h/48h/72h/14 day Holters

A holter is a portable device that records data on your electrical cardiac activity over a period of 24, 48, 72 hours, or 14 days. This test allows your physicians to capture more data on your cardiac activity over a longer period of time compared to a single electrocardiography (ECG) test session.

Contrast Echocardiograpy

Contrast Stress Echocardiography

A contrast stress echocardiogram is a non-invasive cardiac test that combines a stress test and echocardiogram. Ultrasound images of your heart are taken before and immediately after you walk on a treadmill to determine how well your heart and blood vessels are working. A substance called a contrast agent is used to help improve the quality of the images collected. The contrast is administered by a technologist or nurse using an intravenous (IV) line.

Pediatric Cardiac Tests

PACE is pleased to offer pediatric cardiac testing at various locations. At our Barrie and Newmarket clinics, we offer pediatric ECHO, ECG, and Holter Monitor testing. In Orillia, we offer pediatric ECHOs. For a full description of these cardiac tests, please see above. Note: please allow extra time for pediatric testing. All tests are read by a pediatric cardiologist.

Bubble Study

Ambulatory Blood Pressure Monitor

A portable blood pressure unit worn to monitor and record your blood pressure every 20 – 30 mins for a 24 hour continuous period of wear. *Note: this is a $60 non OHIP-covered service

Type 2 Diabetes Clinic

PACE offers a Type 2 Diabetes/Cardio-Metabolic Clinic. The primary focus of the clinic is the management of Type 2 Diabetes in patients with documented vascular disease to improve glycemic control and reduce further cardiac complications.


With the recent opening of the Royal Victoria Regional Health Centre’s expanded cardiac program, please be advised that Barrie now offers basic pacemaker implantation. All complex device implantation (ICDs, leadless, left bundle branch and His bundle pacing, as well as bi-ventricular / cardiac resynchronization therapy) will continue to be offered exclusively at Southlake, along with basic pacemaker implantation. The Southlake Heart Rhythm Program will continue to manage all pacemaker referrals through the Triage office and will distribute some of the referrals made out to Southlake to RVH. For physicians specifically wishing to refer patients for non-emergent device implantation by the Southlake Electrophysiology Team (Drs. Yaariv Khaykin, Atul Verma, Alfredo Pantano and Bernice Tsang), please send these referrals directly to PACE Cardiology (fax 1-855-239-1623).
