How to Use 杜克跑步机评分计算器
Use 杜克跑步机评分计算器 after an exercise treadmill test when exercise duration, ST-segment deviation, and symptom limitation are known. Enter total exercise minutes, ST deviation in millimeters, and the symptom category that occurred during the test.
The page also accepts maximum heart rate and blood pressure change so the result panel can show context, but the Duke score itself is driven by exercise time, ST deviation, and angina index.
Formula & Theory - 杜克跑步机评分计算器
The core calculation is:
Duke treadmill score = exercise time (minutes) - 5 × ST deviation (mm) - 4 × angina index
Angina index: 0 = none, 1 = non-limiting, 2 = exercise-limitingThe Duke treadmill score rewards longer exercise duration and penalizes ischemic ST deviation and exercise-limiting symptoms. Higher scores are generally associated with lower risk, while strongly negative scores suggest higher risk.
The score should be interpreted with the full stress-test report, baseline ECG, medications, symptoms, imaging if performed, and pretest probability. It is not a standalone diagnosis of coronary disease.
Use Cases for 杜克跑步机评分计算器
Use it in sports cardiology, cardiac rehabilitation intake, stress-test education, or quick review of a treadmill report.
It is especially useful for explaining why a long exercise time can offset minor findings, while early limiting symptoms with ST deviation can sharply lower the score.
