title: Modifiers of exercise-induced S-T segment changes.
abstract: Myocardial ischemia due to coronary atherosclerosis is the usual cause of exercise-induced S-T segment changes. A number of drugs, electrolyte alterations, and hemodynamic factors may accentuate or mask these changes. The clinician should keep this in mind during the electrocardiographic interpretation of exercise tests.
