Intermittent ST-segment depressions during adenosine stress test.
ST-segment depression during adenosine stress testing is usually a 1-time event during or after the test and is often related to ischemia due to severe 3-vessel disease. In this case report we describe a patient with severe 3-vessel disease who had intermittent ST-segment depression on the electrocardiogram during a myocardial perfusion stress test with adenosine. These intermittent ST depressions could be explained by possible adenosine-induced coronary spasm.
