What does a 'stress test' consist of?
                     





Dan
idk if there are differnt kinds of stress tests, but i took one several years back and I had to waqlk on this treadmill that got faster and faster like every 30 seconds and they had me hooked upto machines to test whatever...when I was unable to go anymore, they told me to tell them immediately ad they slow it up righ away and stop it...then i had to wear these plugs at home for like 2 days where i was monitored in my daily routine...everything was under my shirt, so you couldnt see it, it just made my shirt kinda bulky, but that is what they did for me, they may do something totally differnt for you, but hope i helped a little...good luck

I had a stress test just a few months ago. This is what they did to me: I had to go to the doctor's office fasting. They put an IV needle in my hand. Through the IV they gave me an injection of solution, to make my veins show up on x-ray. I then waited about 15 minutes so that it could get into my system, then I was placed on a table where there was this big x-ray machine above me that moved and took pictures of my heart.

After this was completed, I went into another room where they hooked me up to a heart monitor and blood pressure cup on my arm. Then I was put on the treadmill which started at a slow pace, then speeded up and elevated it about half way through. The test lasted about 10 or 15 minutes. Then they took me off and set me in a chair, checking my blood pressure and heart rate until it was down to normal.

After the treadmill was completed, they sent me to eat. Telling me to eat something greases so that it would help take the solution out of my body. Had to be back at doctor's office in one hour.

After I ate,they put me back on the same table under that big x-ray machine and took more x-rays.

Got my results from test the next day.

Hope this helps.

The most I know is that you have to spend a lot of time on a tread mill. Wish I could be of more help.

There are several types of stress test. Since you have placed your question under heart disease I am assuming this is the area you were interested in. In this case the test is an ETT or exercise tolerance test. The patient is placed on a tread mill at a steep angle. The speed is increased gradually in aliquots until the duration of the test, which is age dependant is reached, this is called a modified Bruce protocol.. While this is happening a continuous monitor of heart function is taken using an ECG and BP readings are checked. In a positive test ST depression of at least 2mm is recorded on the ECG.

I'm pretty sure it means walking or running on a treadmill while hooked to an EKG machine,

Please see the tutorials on Echocardiography stress test.

Beware of people offering stress tests who are not medical doctors - this is a known tactic of scientologists who will use it to get you interested in the organisation. xpeace

The stress test consist of starting out walking slowly on a treadmill and than the speed is increased, the treadmill is than slanted and you are walking faster, your blood pressure is being taken while you are on the treadmill and in your other heart arm an IV is inserted with some type of dye. The doctor is watching the monitor to see your heart rate. It doesn't hurt but it is tiresome. If you feel that you can't continue walking on the treadmill they will stop the test but try to go as long as you can and place your hands and feets close to the bar on the treadmill . You wear a heart monitor while you are on the treadmill . It helps. You are being monitor to see how your heart acts under stress and other things.

A stress test, sometimes called a treadmill test or exercise test, 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. The test can show if the blood supply is reduced in the arteries that supply the heart. It also helps doctors know the kind and level of exercise appropriate for a patient.
A person taking the test is hooked up to equipment to monitor the heart. walks slowly in place on a treadmill. Then the speed is increased for a faster pace and the treadmill is tilted to produce the effect of going up a small hill.
may be asked to breathe into a tube for a couple of minutes.
can stop the test at any time if needed.
afterwards will sit or lie down to have their heart and blood pressure checked.
Heart rate, breathing, blood pressure, electrocardiogram (ECG or EKG), and how tired you feel are monitored during the test.

Healthy people who take the test are at very little risk. It's about the same as if they walk fast or jog up a big hill. Medical professionals should be present in case something unusual happens during the test.

A physician may recommend an exercise stress test to:

Diagnose coronary artery disease
Diagnose a possible heart-related cause of symptoms such as chest pain, shortness of breath or lightheadedness
Determine a safe level of exercise
Check the effectiveness of procedures done to improve coronary artery circulation in patients with coronary artery disease
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.

Thallium Stress Test

This is a type of nuclear scanning test or myocardial perfusion imaging test. It shows how well blood flows to the heart muscle. It's usually done along with an exercise stress test on a treadmill or bicycle.

The thallium stress test is useful to determine:

Extent of a coronary artery blockage
Prognosis of patients who've suffered a heart attack
Effectiveness of cardiac procedures done to improve circulation in coronary arteries
Cause(s) of chest pain
Level of exercise that a patient can safely perform

When the patient reaches his or her maximum level of exercise, a small amount of a radioactive substance called thallium is injected into the bloodstream. Then the patient lies down on a special table under a camera ("gamma camera") that can see the thallium and make pictures. The thallium mixes with the blood in the bloodstream and heart's arteries and enters heart muscle cells. If a part of the heart muscle doesn't receive a normal blood supply, less than a normal amount of thallium will be in those heart muscle cells.

The first pictures are made shortly after the exercise test and show blood flow to the heart during exercise. The heart is "stressed" during the exercise test — thus the name "stress test." The patient then lies quietly for 2-3 hours and another series of pictures is made. These show blood flow to the heart muscle during rest. If the test is normal during both exercise and rest, then blood flow through the coronary arteries is normal. The coronary arteries supply blood to the heart muscle. If the test shows that perfusion (blood flow) is normal during rest but not during exercise (a perfusion defect), then the heart isn't getting enough blood when it must work harder than normal. This may be due to a blockage in one or more coronary arteries.
If the test is abnormal during both exercise and rest, there's limited blood flow to that part of the heart at all times.
If no thallium is seen in some part of the heart muscle, the cells in this part of the heart are dead from a prior heart attack. (They have become scar tissue.) Sometimes you can't do an exercise test because you're too sick or have physical problems. In this case, a drug such as Dipyridamole or Adenosine is given. This drug increases blood flow to the heart and thus "mimics" an exercise test. Then the thallium test is given.
