A treadmill stress test evaluates how the heart responds to exercise. During the test, heart rhythm, blood pressure, symptoms, and EKG changes are monitored while the patient walks on a treadmill with gradually increasing intensity.
This test may help evaluate chest pain, shortness of breath, exercise tolerance, blood pressure response, rhythm changes, and overall cardiovascular fitness in selected patients.
Symptoms patients may notice
- Chest discomfort or pressure during activity
- Shortness of breath with exertion
- Exercise intolerance, fatigue, or dizziness with activity
- Need to assess safe activity level or treatment response
- Abnormal EKG or risk factors requiring further evaluation
How we evaluate this condition
- Pre-test review to determine whether treadmill testing is safe and appropriate
- Continuous EKG and symptom monitoring during exercise
- Blood pressure and heart-rate response assessment
- Interpretation in context of symptoms and risk factors
Treatment and care options
- Exercise recommendations and risk-factor management
- Medication adjustment when needed
- Further imaging stress test, coronary testing, or referral if treadmill results are abnormal or inconclusive
When to seek urgent care
Call 911 for active chest pain, severe shortness of breath, fainting, or heart attack symptoms rather than waiting for outpatient testing.
