Urgent Appointment Request
We typically have next-day appointment availability.
Continuity of Care
Patients will be seen by cardiologists who will provide long term cardiac care. Patients will not be seen by locums.
Comprehensive Care
Access to our own state of the art non invasive diagnostic testing and access to invasive procedures based out of Southlake Regional Health Centre.
Cardianc Diagnositcs at ORHC
Echocardiography
Echocardiography uses ultrasound waves to image the heart's structure and function, to measure the pressures inside the heart, and to measure the direction and speed of blood flow.
Standard echocardiography acquires a 2D image of a cross section, or slice, of the heart, its chambers and valves, and the large blood vessels of the heart.
Doppler echocardiography bounces sound waves off the blood cells within the heart & blood vessels, to measure the speed and direction of flow.
We are also pleased to offer contrast to improve image quality.
Allow 1 hour for this test.
The test is painless, does not use radiation, and has no known risks.
Stress Testing
An exercise stress test uses an EKG (electrocardiogram) to monitor changes in your heart's electrical activity. We use this to look for signs that your heart isn't getting enough blood flow during exercise. Abnormal test results may be due to coronary heart disease or other factors, such as poor physical fitness.
A technician places sticky patches (electrodes) — which are connected by wires to an electrocardiogram machine — on your chest, legs and arms to record your heart's electrical signals. A cuff on your arm checks your blood pressure during the test. You then exercise on a treadmill until you reach a target heart rate or your maximum effort based on your symptoms.
Allow 30 minutes for this test.
There is little risk of serious harm from stress testing. The chance of causing a heart attack or death is about 1 in 5,000.
Impedit facilis occaecati odio neque aperiam sit
Determine how well your heart tolerates activity & to determine your likelihood of having coronary artery disease. It can also be used to evaluate the effectiveness of your cardiac treatment plan.
During this test, a regular echo as above is first done, then you'll exercise on a treadmill while we monitor your blood pressure and heart rhythm. Immediately after stopping the treadmill, we have you lie on an examination table. The Echo examination is immediately repeated. Images are stored. A video clip of multiple views of the resting and exercise study are compared side-by-side. They are analyzed by the supervising echocardiography specialist
We are also pleased to offer contrast to improve image quality. Allow 90 minutes for the entire test, including the preparation, echo imaging and stress test.
Stress echo poses no known harm from the echo portion & little risk of serious harm from stress testing. The chance of causing a heart attack or death is about 1 in 5,000.
Electrocardiogram
An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart. An EKG shows the heart's electrical activity as line tracings on paper.
Allow 15 minutes for this test.
There are no risks with this test.
Holter Monitoring
This is a battery-operated portable device that measures and records for 24 hours or longer (up to 2 weeks). It measures your heart's activity, such as rate and rhythm.
Allow 30 minutes for the hook up.
There are no risks with this test.
