The human bodied is designed to do certain things when it is stressed. On top of that, various biochemical reactions also take place that can be anticipated. One of the ways your body reacts to stress is for your heart to work harder, or your cardiac output increases. In other words, both heart rate and blood pressure go up to provide the means necessary for the body to deal with the stress. Your doctor chooses to perform a stress test because it is an ideal way to check the health and capability of the heart to withstand higher demands placed upon it.

One type of nuclear stress test involves using Thallium which is a radioactive compound. Do keep in mind that the levels are extremely low and do not cause any harm to the body. Additionally, Thallium's radioactivity decays and it is removed naturally from the body quite quickly.

Thallium, though, allows doctors to create a representation of your heart's chambers so doctors can determine their size. Doctors can judge the health of your heart based on this information. Doctors can also use these images to discover how effective your heart is at pumping blood. Doctors can also determine if there is any heart damage based on these images.

The stress echocardiogram test is useful for doctors because it can provide an accurate image of how well the heart is pumping. Also, the walls of the heart are in plain view and can give more data about the activity and any possible current problems. Just like with other tests, the way the heart acts in a stressed condition is the main thing that will interest most doctors. The EKG is just a basic image of the activity that is going on while the heart is in an stressed out condition. The advantage of this test is that it can show blood flow deficiencies, due to blockage, that may not be detected when other tests are performed.

Various factors can influence the reliability of the isotope stress test.

For example, a target heart rate must be attained, and of course the image quality must be sufficient. When these important factors are present, then a stress test of this kind can allow for a reliable diagnosis in roughly 85% of patients with coronary artery disease. Thus, there is no full guarantee of an accurate diagnosis and as you can see there are other contributing factors. Of course there are also false positives in addition to a range of conditions that can interfere with making an accurate diagnosis.

As you can see, there are numerous uses for the cardiac stress test. Your cardiologist is the best trained person to diagnose what your situation needs. It is also very essential that you know that all tests are limited in some form or another and the cardiac stress test is not an exception. For example, tons relies on the circumstances that should be optimal like getting a wonderful heat rate. Stress tests with images rely on how good the images are. There are also certain natural conditions and situations that can interfere with image quality, as well. This article is brought to you by MaleExtra. To learn more read my thorough Male Extra Review.

Should a person wear medical jewelry if they have Type 2 Diabetes?

I asked this question earlier today, but it left me confused, so here I am willing to try again. I was diagnosed with type 2 diabetes a few weeks ago. She didn't give me a finger pricker thing, but she put me on Metformin and some other medication. The metformin bottle has a little tab on it that says I should be wearing a medical ID tag saying that I'm taking this medicine. Should I be wearing one? I'm probably going to get a finger pricker thing soon. (Sorry, don't know what those are called.)
I'm 13, and I've done quite a bit of research on diabetes. I'm finding everywhere that I should wear a medical bracelet or necklace. Help!
And I'm also allergic to a medicine called Suprax, and I have depression, but like the depression part needs to be on a medical bracelet.

Yes you should!
You should wear a medical bracelet anytime you have a chronic condition or allergy to food or medication..In case you're in an accident or pass out..they will know what to do or not do..
