A stress test, also known as an exercise stress test or a treadmill test, is a diagnostic procedure used to evaluate how well your heart functions during physical activity. The test involves walking on a treadmill or using a stationary bike while your heart rate and blood pressure are monitored. The intensity of the exercise is gradually increased to increase your heart rate and blood pressure. Knowing how well your heart works during physical activity is vital for optimal health, and a stress test can give you insight into this. It’s also an important tool in diagnosing various cardiac conditions.
Electrocardiograms (ECGs) record the electrical rhythms of the heart while you walk on the treadmill. The doctor monitors your vital signs and also examines you for symptoms such as chest pain and fatigue. Abnormalities in blood pressure, heart rate, ECG, or alarming physical symptoms may indicate the presence of CAD (coronary artery disease) or plaque (fatty deposits) in arteries that block the flow of blood to the heart muscle.
A stress test is used to:
All types of stress tests assess heart function by checking heart rate, blood pressure, electrical activity, oxygen levels. There are three primary types of stress tests, and they are are chosen based on the individual’s health condition and needs.
If a patient is unable to exercise, he or she may be prescribed medication to induce the same effect. In this test, they will attach electrodes to the patient’s chest and administer the medication through an IV line in their arm. The medication will increase heart rate and may cause similar side effects to exercise, such as flushing and shortness of breath.
A stress test may be recommended if you have symptoms of heart disease, such as chest pain or shortness of breath, or if you have risk factors for heart disease, such as high blood pressure, high cholesterol, or a family history of heart disease. The results of a stress test can help your doctor determine if you have any underlying heart problems, such as blockages in your coronary arteries or abnormalities in your heart rhythm. It can also help your doctor determine the appropriate treatment for any heart conditions you may have.
A physician may also recommend a stress test if you are :
Both Exercise test and Nuclear test are safe in most cases. However, they may cause adverse effects like a heart attack or an irregular heart rhythm in few patients. Statistics (Ref. Link) show that this happens 1 in 10,000 cases.
There are several situations in which a stress test may not be recommended or may need to be postponed:
Stress tests are important tools that help doctors determine whether someone has an underlying cardiac issue or if they are healthy enough for certain activities. The test itself involves walking on a treadmill while hooked up to an ECG machine, so it’s important to be aware of this before going into the appointment. Knowing what to expect from a stress test—and being prepared for it—can help make sure that you get accurate results from this important medical procedure.
Finally, the reason a stress test is helpful is because it captures the functioning of your heart through different activities, thereby allowing you to see how your cardiac function responds to said activities. Using a smart heart monitor allows you to gather this information for much larger durations of time, giving you more data to get a more accurate sense of your cardiac health.

You will be walking on a treadmill for a stress test, so wear comfortable clothing and running shoes. You also need to stop smoking for at least 24 hours before the test. Talk your doctor a day before about all the medications you use.
You will be asked to walk on a treadmill and the technician increases the speed every few minutes; the technician also increases the incline of the treadmill.
You may be breathing heavily and sweating, but if you begin to feel pain, you must immediately inform the technician. You should not continue the test if you feel any chest pain or dizziness.
It’s normal to feel tired after a stress test, but if you experience chest pain, dizziness, or pain in your neck, jaw, or arm, you should report to the hospital immediately.
Stress tests will help in assessing your heart condition and diagnosing heart problems like CAD, arrhythmias. It also helps in identifying the level of physical activity you are capable of.
