All of the following findings during an exercise tolerance test is associated with left coronary aery disease except ?
An Exercise Tolerance Test (ETT) is an Electrocardiogram (ECG) that is recorded while patient is exercising. A failure to increase SBP by 10 mm Hg, or a sustained decrease in SBP of 10 mm Hg or more, is suggestive of multivessel (or left main) CAD. Findings suggesting high probability of coronary aery disease: Horizontal ST segment depression of 2 mm Down sloping ST segment depression Persistence of ST depression for > 6 minutes into recovery ST segment depression in five or more leads persisting >=5 minutes into recovery. ST-segment elevation of >=1 mm in lead aVR may be a significant predictor of left main coronary aery disease.
Early onset of ST depression
Persistence of ST segment changes late into recovery phase
Failure to increase systolic BP by at least 20mm Hg
ST segment elevation in aVR
Acute coronary syndrome
