About Your Diagnostic Test ...
Our diagnostic testing center offers state-of-the-art technology, including EKG, treadmill testing, nuclear stress testing, T-Wave testing, Holter and event monitoring, rest and stress exercise echocardiography, carotid ultrasound, pacemaker and AICD surveillance, and Ankle Brachial Index.
These non-invasive tests provide our cardiologists with information about the function of your cardiovascular system, so that we may best determine how to protect your heart health.
Pacemaker and Defibrillator Surveillance
The general status of your pacemaker or defibrillator can be checked sometimes by phone – to make sure it is functioning correctly.
Holter Monitoring/Event Monitoring
The Holter monitor is a portable device that continuously records the heart’s rhythm over a 24 hour period. This test monitors all types of arrhythmias and silent ischemia. You will be asked to keep a diary that the physician uses to correlate your activities with symptoms and cardiac rhythms. The Event Monitor is a 30 day auto-triggered monitor to catch those occasional symptoms and arrhythmias.
The major arteries that supply the brain can be easily seen with ultrasound to find plaque deposits and measure any obstruction to blood flow.
An echocardiogram utilizes sound waves to produce a picture of the heart and its valves in motion. Moving a hand-held device across your chest transmits an image that is taped for analysis by your cardiologist. Echocardiograms can reveal the strength of the heart, heart valve problems, cause of enlarged hearts, as well as congenital heart defects, pericardial disease and effects of coronary disease.
Stress Exercise Echocardiography
A combination of treadmill testing and echocardiography, this test offers more diagnostic details about how exercise affects your heart.
Stress Testing: Treadmill
The primary purpose of this test is to evaluate the heart for blockages of the coronary arteries. Treadmill testing evaluates the heart’s response to physical exercise. You will walk on a treadmill, which gradually increases in speed and elevation. During the entire test, your EKG, heart rate rhythm, blood pressure and symptoms are monitored by a physician, nurse or cardiovascular technician.
Pharmacologic Stress Testing: Adenosine
Some patients may not be able to walk on a treadmill safely. A pacemaker, abnormal resting EKG, and certain medications can also interfere with the accuracy of treadmill testing. In these patients, we will perform pharmacologic stress testing. This involves a 6-minute infusion of a medication called adenosine. Adenosine is a natural substance produced in the body. When given for stress tests, adenosine increases blood flow to the heart and provides similar information regarding coronary artery disease as does walking on a treadmill.
Nuclear Stress Testing and Heart Disease
Nuclear cardiology is widely used to establish the diagnosis of heart disease, measure the disease extent, and plan treatment. Nuclear cardiology examinations are used to assess blood flow to the heart, show the size and location of any prior heart attacks and evaluate the pumping function of the heart. These tests are safe and noninvasive.
Imaging uses very small doses of a radioactive imaging agent that is injected into the blood stream. During the examination, you will be asked to rest on a scanning table. A camera will focus on the heart for approximately 20 minutes and measure the amount of imaging material that is taken up by the heart muscle. This is done before and after the treadmill stress test or pharmacologic infusion of Adenosine, for comparison.
T-Wave Alternans Stress Test
The purpose of the T-Wave test is to help identify patients at risk for ventricular arrhythmias that may lead to sudden death. You will walk on a treadmill while your EKG is closely monitored.
THE NIGHT BEFORE OR DAY OF THE TEST.
1. DO NOT USE ANY SKIN LOTIONS OR CREAMS
2. DO NOT TAKE ANY BETA-BLOCKER MEDICATIONS
Examples are Tenormin, Toprol, Lopressor and Coreg.
This is a painless non-invasive test to evaluate blood circulation in the legs. The test uses blood pressure measurements with Doppler Ultrasound to check peripheral pulses. It is indicated for those patients with pain or fatigue in the legs with walking that is relieved by rest or those with non-healing wound ulcers. The ABI is a strong predictor of arterial disease of the heart and brain.
If you are unable to keep your appointment, we ask that you call our office to cancel by 12 pm the day before the scheduled test (or on Friday for Monday examinations). Materials may be ordered for your examination that cannot be used for other patients.
Failure to comply with this cancellation policy may result in a $250.00 charge to you for the materials.
