stress echocardiography

Cardiology An echocardiogram performed when the Pt is exercising. See Radionuclide perfusion imaging.

stress echocardiography

Echocardiography of segments of heart muscle that do not move properly when a patient with coronary artery disease exercises or takes a vasodilating drug (e.g., adenosine or dipyridamole). Stress-induced impairments in regional heart muscle activity are used as markers of obstructions in specific coronary arteries.

9) Indeed, studies have shown that the ability of MRI to predict restoration of myocardial function after revascularization is actually best in segments with the most severe initial dysfunction--exactly the opposite of stress echocardiography.
The sensitivity of dobutamine induced SND was 7% for significant RCA lesion, specificity was 92% and the overall diagnostic accuracy was 65%, these results according to them showed that SND is a relatively common during dobutamine stress echocardiography but its importance as a marker of significant RCA lesion was limited due to the high incidence of false positive results (2).
