Stress Testing

We do Treadmill testing at the office and Nuclear Testing (Lexiscan) at Lakeway Regional Medical Center. Beginning in early 2013, we will have the ability to perform PET testing at the Medical Office Building adjacent to the Lakeway Regional Medical Center.

Treadmill Stress Echocardiogram or Treadmill Stress Test is a test used to determine if there is adequate blood flow to your heart during increasing levels of activity, evaluate the effectiveness of some heart medications, determine the likelihood of having coronary heart disease and the need for further evaluation, identify abnormal heart rhythms, and help you develop a safe exercise program. The patient will walk on a treadmill while being monitored for ECG changes and/or symptoms of angina.

Lexiscan Stress Testing: Lexiscan is a prescription medication that acts as a substitute stressor on the heart. A small amount of radioactive substance is injected into the patient by IV. A special camera will take detailed pictures of your heart. The pictures will show how well blood flows into your heart and if there are any areas of blockage while you lie on your back with your arms above your head. These pictures are done both immediately after the administration of the agent and a second set is taken at rest. Using this technique, areas of the heart that have a decreased blood supply can be detected.
