FAQs
What is the Bruce protocol in a treadmill stress test?
The Bruce protocol is a standardized exercise test that increases treadmill speed and incline every three minutes to progressively stress the heart and assess its response.
How does the Modified Bruce protocol differ from the standard Bruce?
The Modified Bruce starts with slower speeds and lower or zero grades for the first two stages, making it easier for older adults or those new to exercise.
How can I prepare for a treadmill stress test?
Skip heavy meals and caffeine, wear comfortable walking shoes, take medications as directed (ask your doctor about beta‑blockers), and bring a list of all current meds.
What do the results of a treadmill stress test indicate?
Results focus on maximum heart rate achieved, ST‑segment changes on the ECG, and exercise duration. A negative test (no ST changes, high workload) suggests low risk, while positive changes may require further imaging.
Are there risks associated with the treadmill stress test?
Serious complications are rare (<1 in 10,000). Possible issues include arrhythmias, blood pressure drops, or muscle strain, but the test is generally safe when performed under medical supervision.
