dobutamine stress echocardiography
Pronunciation: /doʊˈbjuːtəmiːn/
Pharmacologic stress test using dobutamine infusion combined with echocardiographic monitoring.
Full Definition
Dobutamine stress echocardiography is a pharmacologic stress testing technique that uses incremental dobutamine infusion to increase myocardial oxygen demand while monitoring for inducible wall motion abnormalities with echocardiography. The protocol typically involves increasing dobutamine doses from 5 to 40 mcg/kg/min with atropine added if needed to achieve target heart rate. This test is used when patients cannot exercise adequately and provides both diagnostic and prognostic information about coronary artery disease. The study assesses myocardial viability in addition to ischemia detection.
Usage
Usage note: Often abbreviated as DSE; protocol details should be specified in reports.
