- What is the primary purpose of an exercise stress test?
- To evaluate the heart's response to physical exertion and detect signs of coronary artery disease (ischemia).
- The most commonly used exercise stress test protocol is called the ____.
- Bruce protocol
- How does the Bruce protocol change treadmill settings during the test?
- It increases both speed and incline every 3 minutes in stages.
- What is the standard formula for estimating a patient's maximum predicted heart rate?
- 220 minus the patient's age.
- What percentage of the age-predicted maximum heart rate is the typical target for a submaximal stress test?
- 85 percent.
- What recent cardiac event is an absolute contraindication to exercise stress testing?
- Acute myocardial infarction within the past 2 days.
- What unstable cardiac condition is an absolute contraindication to stress testing?
- Unstable angina.
- What valve condition is an absolute contraindication to stress testing?
- Symptomatic severe aortic stenosis.
- What acute pulmonary condition is an absolute contraindication to stress testing?
- Acute pulmonary embolism.
- What ECG change is considered a positive finding during an exercise stress test?
- Horizontal or downsloping ST-segment depression of 1 mm or more.
- What blood pressure response during exercise should prompt stopping a stress test?
- A drop in systolic blood pressure as workload increases.
- Besides abnormal vital signs, what patient-driven reason can end a stress test early?
- The patient requests to stop due to severe fatigue or intolerable symptoms.
- Which patient population is the Modified Bruce protocol designed for?
- Patients with lower fitness levels, such as elderly or deconditioned patients.
- How does the Modified Bruce protocol differ from the standard Bruce protocol?
- It adds low-intensity warm-up stages before the standard Bruce stages begin.
- When is a pharmacologic stress test used instead of an exercise stress test?
- When a patient is physically unable to exercise adequately.
