Stress Test:

A stress test is also called as a treadmill test or exercise test that helps a doctor find out how well your heart handles work. As your body works harder during the test, it requires more oxygen, so the heart must pump more blood and due to this the test can show if the blood supply is reduced in the arteries that supply the heart. This test makes it easier for the doctors to know the kind and level of exercise appropriate for a patient.
What does a person do while taking the test?
A person taking the test is hooked up to an equipment to monitor the heart. He walks slowly in place on a treadmill and then the speed is increased for a faster pace and the treadmill is tilted to produce the effect of going up a small hill. Sometimes he may be asked to breathe in a tube for a couple of minutes. This test can be stopped at any time if needed. After this process he will sit or lie down to have his heart and blood pressure checked. Later your heart rate, breathing, blood pressure, electrocardiogram and even how tired you feel are monitored during the test. There is a little risk for healthy people who take the test. For them it's about the same as if they walk fast or jog up a small or big hill. But it is very important that medical professionals should be present during the test in case something unusual happens.
After a test a physician may recommend an exercise stress test for various reasons:
To diagnose a coronary artery disease.
To diagnose chest pain, shortness of breath or lightheadedness, high blood pressure which are heart-related problems.
To determine a safe level of exercise that will not cause any problems to your health.
To check regularly the effectiveness of procedures done to improve coronary artery circulation in patients with coronary artery disease or any other related to it.
It is important to predict risk of dangerous heart-related conditions such as a heart attack.
Depending on the results of the exercise stress test, the physician may recommend more tests such as a nuclear stress test or cardiac catheterization doctors to know the kind and level of exercise appropriate for a patient.
