An electrocardiography test (also known as an “ECG” or an EKG” records the electrical activity of your heart and can detect whether there may be any abnormal patterns associated with heart disease. It is completed by placing electrodes on the patient’s chest, which can then record the electrical changes that occur as the heart beats. It can also detect electrical abnormalities commonly known as “arrhythmia” that patients sometimes may or may not feel.

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 cardiac exercise testing on our specialized medical treadmills. While exercising, your body will work harder than normal, and your heart will need to pump faster and harder to deliver the oxygen necessary to support the rest of your body. This will allow us to determine the appropriate level of exercise for you, as well as determine whether there is a blood flow reduction in the arteries supplying the heart.

Physicians will also order this test to see how you are responding to certain medications you may be taking and/or monitor your blood pressure under physical activities. This test also monitors the electrical function/conduction of your cardiac cells and allows our cardiologists to determine many different cardiac and non-cardiac factors.


An echocardiography test uses ultrasound to image your heart while it beats, similar to an ultrasound that checks for the health of a baby during pregnancy. Echocardiography is a non invasive test 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 any tissue damage. This test can help detect many heart diseases, helps with cardiac management and follow up management of patients with any suspected or known heart diseases.

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. Its main purpose is to assess the wall motion of your heart in response to physical stress (on the treadmill). Stress echocardiography is also 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 echocardiogram test session.

Event Loop Monitoring

An event loop monitoring test is similar to a holter test in that we use a portable device to continuously monitor and record your cardiac activity. The difference with an event loop monitor is that when you experience symptoms of a cardiac problem, such as a palpitation and/or chest discomfort, you press a button on the recording device so that your physician can see exactly what your cardiac activity looks like at that exact moment and use that data for further analysis. This device is worn for 14 days or up to 30 events recorded on the monitor.

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 $50 non OHIP-covered service

Type 2 Diabetes Clinic

PACE Barrie is pleased to announce the opening of 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. To make an appointment, please call 705-721-4422 or fax your referral to 1-705-721-5577.
