title: Exercise-induced S-T segment alterations.
abstract: The S-T segment response remains the most important exercise variable. In this article, the four types of abnormalities that can occur are reviewed, and there is a discussion of the diagnosticity and predictive value for future coronary events when such abnormalities occur. Finally, there is a discussion of perhaps the most important use of exercise testing--estimating the extent of disease.
