CAD when resting EKG is abnormal
ischemia after infarct

imaging is done prior to test and _______ long after treadmill
1 min
Equipment
echocardiogram treadmill 12 lead CPR equipment imaging bed
personnel present during test
physician
echo tech
stress tech
medications
patients are expected not to have a heavy meal before test
decision on continuing medications will be made by the referring physician.
normal response to progressive exercise
increase in myocardial contractility and wall thickening in some segments
development of new wall motion with exercise abnormally compared to the rest of the study is considered
ischemia
sensitivity of a stress echo compared to a nuclear perfusion
85-90 %
dobutamine
increases heart rate
