Patient Information

Electrocardiogram (ECG)

Also called an ECG (or EKG),an electrocardiogram is a simple, painless test that monitors and records cardiac activity and rhythm of the heartbeat using the heart’s electrical signals.

See Instructions

Special Instructions

We do ask that you refrain from wearing perfumes, colognes or scented lotions on the day of your appointment. There are no pretest dietary restrictions and you should continue to take any prescribed medications as normal, unless otherwise advised by your doctor.

Test Process

The entire test will take about 10 to 15 minutes.

An electrocardiogram is a safe and painless test done while you are lying face-up on an examination table. In preparation, a technician will place receptors on your chest, arms, and legs. Depending, the technician may have to shave areas of your skin (male patients) to help the receptors stick. Patients are provided with a gown for privacy.

Following an ECG, you may develop redness where the receptors were attached. This mild redness often goes away quickly and without treatment.

Patients are typically able to return to work or other activities immediately following an ECG.

Please arrive 10 minutes before your test to register at the reception desk. Bring your health card and your requisition form (if your physician has provided you with one).

Holter Monitoring (Ambulatory ECG Monitoring)

A Holter monitor is similar to an ECG (electrocardiogram). However, a standard ECG only records the heartbeat for a few seconds while a Holter Monitor will record longer to diagnose arrhythmias, in order to detect silent (symptomless) myocardial ischemia and to evaluate whether current treatments for an arrhythmia or silent myocardial ischemia are working.

See Instructions

Special Instructions

A Holter Monitor is a small, portable device that is worn while you do your normal daily activities in order to monitor the heart over a longer period of time.

Prior to being equipped with the Holter, we suggest taking a shower as you will not be able to shower during the period in which you are wearing the device (typically 24, 48 or 72 hours).

We do ask that you refrain from wearing perfumes, colognes or scented lotions on the day of your appointment. There are no pretest dietary restrictions and you should continue to take any prescribed medications as normal, unless otherwise advised by your doctor.

2D Colour Doppler Echocardiography (Echo)

Doppler Echocardiography is a procedure that uses Doppler ultrasonography to examine the heart with high frequency sound waves to create an image. A 2D (or two-dimensional) echocardiogram is capable of displaying a cross-sectional “slice” of the beating heart, including the chambers, valves and the major blood vessels that exit from the left and right ventricle.

See Instructions

Special Instructions

Other than wearing loose-fitting clothing, there are no special restrictions or preparation prior to a 2D Doppler echocardiogram. Although the gel is water soluble and should not stain, it can be messy and could get on your clothing, so please be aware and dress appropriately.

We do ask that you refrain from wearing perfumes, colognes or scented lotions on the day of your appointment. There are no pretest dietary restrictions and you should continue to take any prescribed medications as normal, unless otherwise advised by your doctor.

Exercise Stress Testing

Exercise stress testing is an important tool in the evaluation and management of patients with known or suspected coronary heart disease. While stress testing can be performed in a variety of ways, the most commonly used are electrocardiography and exercise combined with imaging.

See Instructions

Special Instructions

We ask that you wear comfortable clothes that you are able to move freely in, as there will be physical activity during the test.

We also ask that you refrain from wearing perfumes, colognes or scented lotions on the day of your appointment.

There are no pretest dietary restrictions and you should continue to take any prescribed medications as normal, unless otherwise advised by your doctor.

Ambulatory Blood Pressure Monitor

An ambulatory blood pressure monitor is a portable blood pressure recording device that provides doctors information about your blood pressure over a 24-hour period. An ABPM is used to detect high blood pressure (hypertension) or low blood pressure (hypotension) in an individual.

See Instructions

Special Instructions

Ambulatory blood pressure monitors are delicate and expensive medical devices. As such, you will be asked to sign a responsibility form to ensure that you will return the device on time and in working condition.

We do ask that you refrain from wearing perfumes, colognes or scented lotions on the day of your appointment.

There are no pretest dietary restrictions and you should continue to take any prescribed medications as normal, unless otherwise advised by your doctor.

Cardiac Consultation

A cardiac consultation is an opportunity for you to be evaluated by a specialist of cardiology, who has the expertise and training to help 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. Should it be determined that further tests are warranted, your cardiologist will requests tests.

See Instructions

Special Instructions

Bring arrive with ALL OF YOUR PRESCRIPTION MEDICATIONS for the cardiologist to review.

We do ask that you refrain from wearing perfumes, colognes or scented lotions on the day of your appointment. There are no pretest dietary restrictions and you should continue to take any prescribed medications as normal, unless otherwise advised by your doctor.

Arrive 10 minutes before your appointment to register at the reception desk.

Nuclear Stress Test

Nuclear Stress Test is a non-invasive imaging test performed to find out whether any areas of the heart muscle are not receiving enough blood flow during exercise.

See Instructions

Special Instructions

Patients should be off beta- blockers and calcium-channel blockers on the recommendation of the referring physician only. For patients who have severe asthma and who are on chronic bronchodilators, Persantine stress studies are contraindicated. Patients undergoing Persantine stressing do not require exercise clothing.

Patients should have a light meal on the day of the test. Avoid certain foods such as milk and caffeine-containing beverages at least 24 hours before the test. No caffeine containing products (e.g.: coffee, tea, hot chocolate, even decaffeinated drinks, soda pop, some pain pills and asthma medications) 12 hours prior to the test.

Bring a list of medications with you including dosage and frequency. Take all medications as usual unless otherwise directed by your doctor. It is vital that the physician knows exactly what medications you are taking and if you have diabetes, a defibrillator or pacemaker.  

Make sure that you have no lotions applied on your chest area and no smoking 1 hour prior to testing.

Please bring a snack with you to eat after receiving your radio-pharmaceutical injection for the test. This will help to optimize the quality of your images.

Make sure you wear comfortable clothing suitable for physical activity. Your shoes should be designed for running or jogging (excluding Persantine patients).

Test Process

The Nuclear Cardiology examination consists of two parts which last approximately 3-6 hours in total duration.

The Resting MUGA (ventricular function) study consists of one part and lasts about 1-1/2 hours.

Ventricular Function Studies

This test evaluates blood flow in the heart and the pumping function of the heart at rest. It requires no preparation and last about one hour.
