How do I read my stress test results?
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.
What does ergometry measure?
Exercise physiology
Ergometry (from Greek ergos=work and metry=to measure) is the measurement and quantification of human physical performance. Traditionally, ergometric measurements evaluate the endurance capabilities of a person, although strength capabilities can also be quantified using appropriate tests.
How do you interpret an ECG stress?
Interpretation of the treadmill ECG stress test
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 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 a positive stress test?
An ECG stress test is considered positive for ischemia if there is at least a 1-mm horizontal or down-sloping ST-segment depression. Up-sloping ST-segment depression is not considered a positive finding. An ST-segment elevation greater than 1 mm is highly suggestive of significant ischemia.
What does a positive stress test look like?
Possible results of the exercise stress test include: normal blood flow during exercise and rest. normal blood flow when resting but not during exercise, possibly indicating a blocked artery. low blood flow when exercising and resting, suggesting coronary artery disease.
Why is Ergometry important?
Ergometry can help physiologists understand the energy expenditure and energy cost of performing specific exercises. The data can then be used to build better, more efficient training programs and regimens.
What is work rate on cycle ergometer?
cycle ergometer must be properly calibrated. leg cycling between watts (300 and 1200 kgm/min) arm cycling between 25 and 125 watts (150 to 750 kgm/min)
What is the purpose of the cycle ergometer test?
The YMCA cycle ergometer test is a nationally used submaximal test that measures heart rate response to an increasing exercise workload. Two exercise heart rates are used to estimate maximal physical working capacity. A workload guide was established to make testing more efficient.

Does a stress test show blockages?
“Most people think a stress test identifies blockages to the heart, but it does not,” explains Aristotelis Vlahos, M.D., director of the Cardiac Catheterization Lab at Riverview Medical Center. “It looks at blood flow to the heart muscle and determines if blood flow is adequate or not.
What is a negative stress test?
A negative test result indicates a normal test which significantly decreases the likelihood of coronary artery disease. Positive. A positive test result occurs where a diagnosis of coronary artery disease (IHD, angina) is definite. Inconclusive.
What is a good METs score for a stress test by age?
A healthy 50-year-old man should have a capacity of at least 9.2 METs; a healthy 50-year-old woman should clock in at 8.2 METs or higher, according to a recent study on women’s fitness in the New England Journal of Medicine. For men age 20, 13.5 METs; age 30, 11.4 METs; age 40, 10.3 METs.

Is 9 minutes on a treadmill stress test good?
The FAA does accept a minimum of 85% of maximum predicted rate, but stay on the treadmill as long as possible, up to nine minutes to demonstrate maximum effort. “The FAA allows for applicants over age 70 to exercise for at least six minutes, but must still attain 85% of predicted maximum heart rate.”

What is a normal blood pressure response during exercise testing?
In the present study peak values of the systolic blood pressure during multistage exercise test did not exceed 190 ± 20 mmHg in women and 210 ± 20 mmHg in men [8, 12, 21, 22].
How high can blood pressure go while exercising?
Normally during exercise, blood pressure increases to push the flow of oxygen-rich blood throughout the body. However, in some individuals, the response to exercise is exaggerated. Instead of reaching a systolic (upper number) blood pressure of around 200 mmHg at maximal exercise, they spike at 250 mmHg or higher.
What exercises should be avoided with high blood pressure?
Exercises to avoid
For example, any exercise that is very intensive for short periods of time, such as sprinting or weightlifting. They raise your blood pressure very quickly and put too much strain on your heart and blood vessels.
