Tilt-Table Test

A tilt-table test will help to determine the cause of your lightheadedness, dizzy spells or fainting episodes. The tilt-table test tries to duplicate symptoms you have experienced under controlled conditions. To do the test, you will be placed on a table and the table will be moved upright so that you are standing. You will be closely monitored for changes in your blood pressure and heart rate. Safety straps will be fastened across your chest, waist and legs. If you experience any symptoms such as nausea or dizziness, let the medical assistant and/or physician immediately.

Lexiscan Nuclear Stress Test

A Pharmacological or medication stress test will be performed using the drug Lexiscan. Lexiscan has the effect of dilating blood vessels to simulate exercise. Electrodes will be placed on your chest and connect wires to an EKG machine to monitor your heart rhythm. A blood pressure (BP) cuff will also be placed around your arm to monitor your BP throughout the test. Lexiscan will be administered through the IV over a 1 minute period. Side effects include facial flushing, chest heaviness, shortness of breath, headache and sometimes stomach cramps. These side effects, if you should have any, will only last a few minutes. Report any of the above symptoms to the tech as the testing is occurring. Midway through the infusion of Lexiscan a second radionuclide will be injected into the IV. Once the Lexiscan is complete any side effects that have occurred should resolve within 2-3 minutes after the medication has been stopped. Your blood pressure and EKG will be monitored for several more minutes after the medication has been infused. You will lie under the camera again for a second set of images.

Cardiolite Stress Test

The Cardiolite stress test is a diagnostic exam to evaluate the supply of blood to your heart muscle. Your heart receives blood from the coronary arteries. If these arteries become partially blocked or narrowed, your heart will not receive the blood that it needs for the proper function. This test may be useful in detecting the presence and significance of coronary artery disease.
