Comparative StudyProlongation of the QT-corrected interval during dobutamine stress echocardiography: a marker for ischemia.
Dobutamine stress echocardiography (DSE) has become a very reliable non-invasive tool in the diagnosis of ischemic heart disease based on the determination of new wall motion abnormalities rather than electrocardiographic changes. ⋯ These results suggest that the development of new wall motion abnormalities suggestive of ischemia during DSE is associated with prolongation of the QTc interval and delayed heart rate early in the recovery period. These two parameters should be further studied not only as additional markers in the identification of ischemia in patients referred for DSE but also to assess their potential significance during short- and long-term follow-up.
