title: Exercise-induced ST-segment depression and elevation in the same patient. A case for mixed angina.
abstract: A patient with significant left anterior descending coronary disease is presented who developed significant ST segment elevation and depression at different times under similar testing conditions. Currently proposed explanations for exercise-induced ST segment elevation are discussed. This patient likely represents a case of spasm superimposed on significant obstructive disease, so-called mixed angina.
