Whither the ST segment during exercise?
THE WIDESPREAD POPULARITY of using the ST-segment response to exercise to detect individuals with ische-mic heart disease is based largely on epidemiologic data and arteriographic correlative studies. Epidemiologic studies of asymptomatic individuals have shown that the presence of a positive ST-segment response to exercise distinguishes a group of individuals at relatively high risk of develop...
متن کاملExercise electrocardiogram testing: beyond the ST segment.
Exercise testing remains the most widely accessible and relatively inexpensive method for initial evaluation of suspected coronary disease and for evaluation of its severity.1–3 Clinical usefulness has been limited, however, by poor sensitivity of standard ST-segment depression criteria for assessment of anatomic and functional coronary disease severity and for prediction of risk.1,2,4–6 Recent...
متن کاملAsymptomatic Episodes of ST Segment Depression Occurring During Daily Life and During Exercise
Background. Silent myocardial ischemia is an adverse prognostic marker in patients with coronary disease; however, controlled data on the effect of treatment are sparse and contradictory, and the relations among the occurrence of ST segment depression, drug efficacy, and heart rate are unclear. Methods and Results. Sixty patients with stable coronary artery disease, a positive treadmill exercis...
متن کاملComputer quantitation of the ST-segment response during maximal treadmill exercise. Clinical correlation.
The ST-segment response during maximal treadmill exercise was quantitated by digital computer after excessive noise in the electrocardiographic data was reduced by computer averaging. Both the slope and the depression were quantitated. Two groups of subjects were studied. Group A consisted of 35 subjects between 33 and 57 years of age with confirmed or suspected coronary artery disease. Group N...
متن کاملClinical implications of ST segment time-course recovery patterns during the exercise stress test
The exercise stress test (EST) is the commonest non-invasive test to elucidate the nature of chest pain/discomfort. ST segment depression provides evidence of ischemia, but is hampered by a significant number of false negative and false positive tests. This study evaluated patterns and duration of ST depression in an attempt to differentiate false positive and false negative tests. One hundred ...
