When you’re resting, your heart may seem to be working perfectly normally. But when you exercise, your heart has to work harder and pump more blood throughout your body. A treadmill stress test, also called an exercise stress test, allows your cardiology team to see how your heart performs when its workload increases.
At Coastal Heart Medical Group, treadmill stress testing is one of the tools we use to evaluate heart health, investigate certain symptoms, and help determine the best next steps for our patients.
A treadmill stress test monitors your heart while you walk on a treadmill. During the test, electrodes are placed on your chest to continuously record your heart’s electrical activity with an electrocardiogram (EKG or ECG). Your heart rate, blood pressure, symptoms, and overall response to exercise are also monitored.
The treadmill gradually increases in speed and incline, making your heart work progressively harder. Your care team watches closely for changes that may provide important information about how your heart responds to physical activity.
Your cardiologist may recommend a treadmill stress test if you have symptoms or risk factors that could be related to heart disease.
A stress test may be used to:
Not everyone with heart disease experiences obvious symptoms at rest. Exercise places additional demand on the heart, which can sometimes reveal abnormalities that aren’t apparent while you’re sitting or lying down.
Before the test begins, your care team will place electrodes on your chest and take baseline measurements of your heart rate and blood pressure.
You’ll then begin walking on the treadmill at a manageable pace. At regular intervals, the treadmill will become faster and/or steeper. Throughout the test, your EKG, heart rate, blood pressure, and symptoms will be monitored.
You should tell the medical team immediately if you experience symptoms such as chest discomfort, unusual shortness of breath, dizziness, or significant fatigue.
The exercise portion of the test is typically relatively short, although your entire appointment will take longer to allow time for preparation and recovery.
Your healthcare team will provide specific instructions before your appointment. You may be asked to avoid eating a large meal shortly before the test and to limit caffeine or certain medications depending on the type of testing being performed.
Wear comfortable clothing and supportive shoes that are appropriate for walking on a treadmill.
Do not stop any prescribed heart medication unless your healthcare provider specifically instructs you to do so.
After you finish exercising, your heart rate and blood pressure will continue to be monitored as you recover.
Your cardiologist will review the results along with your symptoms, medical history, and other cardiac testing. Depending on the findings, no additional testing may be needed, or your doctor may recommend further evaluation.
A treadmill stress test is only one piece of the overall picture. Your cardiologist will determine which testing approach is most appropriate for your individual health needs.
If you’ve been experiencing chest discomfort, shortness of breath with activity, or other concerning symptoms, don’t ignore them. Evaluating your heart health early can help identify potential problems and guide appropriate treatment.
