24Hour Holter Monitoring
A Holter monitor is a recording device which is attached to your skin by ECG electrodes. It is able to record the heart rhythm
over a 24-hour period. You will record any symptoms that occur during that time. The recording is then downloaded and
analyzed. It may detect changes in heart rhythm, or changes in the ECG that might mean lack of blood supply to the heart.
Echocardiography is an ultrasound test that gives excellent pictures of the structures of the heart. It evaluates the size, shape
and motion of these structures. Important information may be obtained on the function of the pumping chambers of the heart
and of the valves. In conjunction with two dimensional imaging, Cardiac Doppler may be used to find leaky cardiac valves
and/or the presence of tightened or stenotic valves. During the Echocardiogram, a transducer (a small instrument looking
something like a stethoscope) coated with conductive jelly will be placed on the chest and moved along the chest wall over
the areas to be examined. The test is entirely painless and safe and takes about 20 to 30 minutes.

Pharmacologic Nuclear Stress Testing
In patients who cannot exercise due to vascular or musculo-skeletal problems (e.g. back pain, arthritis, etc.) an injection of intravenous adenosine or regadenoson may be used to "stress" the heart. The radioactive tracer may then be administered and the heart scanned with a special camera to identify areas of reduced coronary artery blood flow.
Vascular Ultrasound is a high-resolution ultrasound test which provides critical anatomic and hemodynamic information.
This test is most frequently used to identify and characterize blockages in the carotid arteries (which supply blood to the
brain) or the arteries in the legs. With this analysis, detailed data regarding percent blockage and characterization of
atheromatous plaque are provided. The veins may also be studied to assess for blockages or incompetent valves.
Exercise Nuclear Stress Testing
Nuclear Stress testing is a form of a treadmill test that may provide added useful information about your prognosis. A radioactive tracer is injected into your blood stream while you exercise on the treadmill. The material is safe and medically approved. Similar materials are used to obtain bone scans, brain scans, thyroid scans etc. The radioactive tracer is taken up by your heart and is distributed through the heart muscle according to blood flow. Areas of the heart that are supplied by narrowed arteries will have reduced blood flow that will show up on scanning as reduced areas of radioactivity. These techniques are more accurate than routine treadmill testing in finding coronary disease and determining its severity. Nuclear scanning has the added advantage of providing information on the pump function of the heart.
