Exercise stress test

From Wikipedia, the free encyclopedia

An exercise stress test (EST) is an evaluation modality used in cardiology in which the ability of the heart to respond to stress, either actually induced by exercise or stimulated by pharmacologic maneuvers, is measured in a controlled clinical setting. The image created by its recording is known as an electrocardiogram or ECG.

The test is typically included in the initial evaluation of suspected ischemic heart disease, and as a prognostic indicator after myocardial infarction.^[1]
