A stress echo is a study whereby the function of the LV is at rest and during exercise. The heart is charged by means of dobutamine intravenously. Dobutamine is a catecholamine with predominant β - receptor stimulator which positive inotropic, chronotropic and dromotropic effects caused by the heart. Dobutamine is the half-life of approximately 2 minutes. The inotropic and chronotropic effects induce myocardial ischemia in a significant narrowing of a coronary artery. Echocardiography than regional wall motion detect disorders. DSE is also used to detect contractile reserve on myocardial damage after infarction. The betrouwbaardheid for detecting coronary stenosis can be compared with myocardial perfusion scintigraphy and DSE is superior to exercise ECG. | A stress echo is a study whereby the function of the LV is at rest and during exercise.
