Nuclear Stress Testing

A stress test, sometimes called a treadmill test or exercise test, helps a doctor find out how well your heart handles work. As your body works harder during the test, it requires more oxygen, so the heart must pump more blood. The test can show if the blood supply is reduced in the arteries that supply the heart. It also helps doctors know the kind and level of exercise appropriate for a patient.

Cardiac catheterization

Cardiac catheterization (cardiac cath or heart cath) is a procedure to examine how well your heart is working. A thin, hollow tube called a catheter is inserted into a large blood vessel that leads to your heart.

CAT Scan

CT is a noninvasive test that uses X-rays to make pictures of your heart. Modern CT scanners (multidetector CT, or MDCT) work very fast and detailed. They can take images of the beating heart, and show calcium and blockages in your heart arteries.

Chest X-ray

What is it? A chest X-ray is a picture of the heart, lungs and bones of the chest. A chest X-ray doesn’t show the inside structures of the heart though.

Why is it done? A chest X-ray shows the location, size and shape of the heart, lungs and the blood vessels.

How is it done? A technologist positions you (a hospital gown may be worn over the chest) next to the X-ray film. Older children will be asked to hold their breath and be very still for two or three seconds; infants may require some restraint. An X-ray machine will be turned on for a fraction of a second. During this time, a small beam of X-rays passes through the chest and makes an image on special photographic film. Sometimes two pictures are taken — a front and side view. The X-ray film takes about 10 minutes to develop. Sometimes your cardiologist needs more than just the front and side chest X-rays.

Coronary Angiogram

The coronary arteries supply your heart muscle with blood. They can become clogged from a buildup of cholesterol, cells or other substances (plaque). This can reduce the flow of blood to your heart. If a blood clot forms and blocks blood flow through that artery, a heart attack may occur.

CT Scanning

A CT scan is an X-ray imaging technique that uses a computer to produce cross-sectional images. Also referred to as cardiac computed tomography, computerized axial tomography or CAT scan, it can be used to examine the heart and blood vessels for problems. It is also used to identify the blood vessels in the brain affected by stroke.

Dobutamine Stress Test

Dobutamine echocardiogram is a painless, harmless test that uses a dobutamine infusion to mimic the effect of exercise on your heart.

What is it? An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers. The right and left atria or upper chambers make the first wave called a “P wave" — following a flat line when the electrical impulse goes to the bottom chambers. The right and left bottom chambers or ventricles make the next wave called a “QRS complex." The final wave or “T wave” represents electrical recovery or return to a resting state for the ventricles.

Why is it done? An ECG gives two major kinds of information. First, by measuring time intervals on the ECG, a doctor can determine how long the electrical wave takes to pass through the heart. Finding out how long a wave takes to travel from one part of the heart to the next shows if the electrical activity is normal or slow, fast or irregular. Second, by measuring the amount of electrical activity passing through the heart muscle, a cardiologist may be able to find out if parts of the heart are too large or are overworked.

How is it done? No. There’s no pain or risk associated with having an electrocardiogram. When the ECG stickers are removed, there may be some minor discomfort.

ECG Stress Testing

A monitor with electrodes that are attached to the skin on the chest area to record your heart function while you walk in place on a treadmill. Many aspects of your heart function can be checked including heart rate, breathing, blood pressure, ECG (EKG) and how tired you become when exercising.

Echocardiographic Stress Testing (Treadminll)

An echocardiogram is a painless, harmless test that uses high frequency sound waves (ultrasound) to examine the heart’s anatomy and function. A treadmill stress test evaluates your heart’s response to physical activity through the monitoring of your heart rate, blood pressure, and electrocardiograms while you exercise on a treadmill.

When the two tests are combined, an assessment can be made of the status of your heart at rest, as well as during and immediately following stress. This can provide your doctor with information regarding whether or not you have significant blockages in your heart arteries. Other information obtained includes an assessment of the pumping function of your heart and the status of your heart valves.

What is an echocardiogram? An echocardiogram (echo) is a test that uses high frequency sound waves (ultrasound) to make pictures of your heart. The test is also called echocardiography or diagnostic cardiac ultrasound.

Holter Monitor

An ambulatory electrocardiogram (EKG or ECG) records the electrical activity of your heart while you do your usual activities. (Ambulatory means that you are able to walk.) Ambulatory monitors are referred to by several names, including ambulatory electrocardiogram, ambulatory EKG, Holter monitoring, 24-hour EKG, or cardiac event monitoring.

Magnetic Resonance

Magnetic resonance imaging (MRI) is a noninvasive test that uses a magnetic field and radiofrequency waves to create detailed pictures of organs and structures inside your body. It can be used to examine your heart and blood vessels, and to identify areas of the brain affected by stroke. Magnetic resonance imaging is also sometimes called nuclear magnetic resonance (NMR) imaging.
