What and Why Are Stress Tests Used
A Gander at Cardiac Stress Tests
What else do you wish you understood about Heart Attack ? Heart Attack is a comprehensive topic, with both basic factors and other fascinating points. In this blog we discuss it all. Many readers and enthusiasts find that this web site is a terrific starting point if you are brand-new to the subject.
A stress test using low dosage radioactive chemicals on the heart is known as a nuclear stress test. The idea behind the test is get a clear representation of blood flow through the heart.
Doctors perform such tests on patients because they wish to discover whether blood flow has been diminished. If blood flow is lower than regular, this serves as an alarm that there is a restriction, either in the heart or other arteries. Nuclear tests can be performed on patients during exercise or while at rest. The name of stress test comes from the fact that exercising places pressure on the cardiovascular system.
One test, the nuclear stress test, measures the flow of blood towards the heart. This test is designed to measure the heart's blood flow in "at rest" and exercise conditions. Also, this test is unique in that images are produced and made possible due to the radioactive compounds used in the test; hence the name, nuclear stress test. There are two conditions that need to be tested which is why it is important to conduct the test at rest as well as during exercise. There are a few differences such as the fact that the imaging aspect is performed immediately after exercising on a treadmill. This is so that the images capture the heart while it is still being stressed.
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 other like tests, most doctors are drawn to how the heart responds while in a stressed position. The EKG just provides a snapshot of how the heart is performing while in a stressed manner. The thing that makes this test beneficial is that it can pick up on blood flow abnormalities that other tests might not have picked up on in relation to blockages.
Regular stress tests use what is known as an EKG or electrocardiogram. This device leaves a little room for interpretation. Sometimes, changes in the EKG can be caused by things that are not at all related to heart disease. Doctors may have to make some tough decisions about the testing process if there are things showing up out of the ordinary during the "at rest" phase of testing. More often than not all doctors really need is to order a different type of test for stress. However, the regular stress test is certainly applicable and reliable for many patients. A doctor specializing in cardiology will then look over the results to determine the presence of any issues that could be structural or functional in nature. A nuclear stress test image will show a big contrast between areas that have restricted or reduced blood flow and those that have regular blood supply, which is why they are so useful.
