What is the normal range for stress test?
The normal ranges of blood pressure response to exercise stress testing are as shown in Figure 1. Normal systolic and diastolic responses to exercise stress testing should not exceed 220 and 100 mm Hg, respectively. Systolic blood pressure of >230 mm Hg is generally considered hazardous.
What is considered an abnormal stress test?
An abnormal result, which means your heart’s blood flow is insufficient, may occur only during the exercise phase of your stress test. During rest, your blood flow may be normal, but during strenuous activity, when your heart is working harder, it may not be getting the blood supply it needs.
What is a normal Duke score?
A Duke treatment score ⩾5 indicates low risk for cardiovascular events (predicted 4 year survival was 99%). This population does not need further investigation with coronary angiography. A score <–10 indicates high risk for cardiovascular events (predicted 4 year survival was 79%).
What is a Duke score on a stress test?
The Duke Treadmill Score is a weighted index using treadmill exercise time (performed according to the standard Bruce protocol), maximum net ST-segment deviation (depression or elevation), and exercise-induced angina.
What is a positive stress ECG?
Positive or abnormal: Doctors may conclude the stress test is positive for cardiac ischemia—meaning the heart muscle wasn’t getting adequate oxygenated blood during the stress. There are certain ECG and imaging changes that would support this conclusion.
How do you read a stress test?
The results of an EST are usually reported as either negative, positive or inconclusive. A negative test result indicates a normal test which significantly decreases the likelihood of coronary artery disease. A positive test result occurs where a diagnosis of coronary artery disease (IHD, angina) is definite.
What is abnormal stress ECG?
A treadmill ECG stress test is considered abnormal when there is a horizontal or down-sloping ST-segment depression ≥ 1 mm at 60–80 ms after the J point. (9) Exercise ECGs with up-sloping ST-segment depressions are typically reported as an ‘equivocal’ test.
What is a good Duke score?
How do you read a stress test report?
Possible Conclusions
- Positive or abnormal: Doctors may conclude the stress test is positive for cardiac ischemia—meaning the heart muscle wasn’t getting adequate oxygenated blood during the stress.
- Negative or normal: A negative test result lacks any of the things that could trigger a positive conclusion.
