The cardiac stress test is the most significant tool cardiologists have at their disposal to diagnose any kind of heart disease. Medical doctors must work together with highly trained technicians in order to get the best possible results from the stress test. There are distinctive types of stress tests and each one has very specific requirements.
Not only do the specific tests involved influence the reliability of the diagnosis but also the conditions of the testing as well. One thing the medical professional is trying to detect, or determine, is how much stress the heart can endure before there is evidence of abnormal heart behavior or functions. The most widely familiar to the general public is the exercise stress test but it has one application that it is primarily suited for.
The general stress test is a procedure that is not as hard as other types of stress tests like the nuclear stress test. During the administering of a general test such as the treadmill or bicycle test, the patient’s heart must be examined. It can be watched with an EKG or ECG monitor. Then the patient walks in a normal manner on the treadmill. Gradually, the speed of the treadmill is boosted so that the demand on the heart goes up or the heart is under stress. While is going on, a medical doctor is in the room conducting tests and available just in case anything might go wrong. Also, while this is going on, the blood pressure and rate of the patient is closely supervised.
With the help of Thallium, doctors can get a fairly accurate idea of the size of the chambers in your heart. Doctors can judge the health of your heart based on this information. In addition, medical practitioners will gain insights into the ability of the heart to pump blood. Based on these images, doctors can also tell if the heart is suffering from any damage. Health professionals demand stress tests in an effort to understand the state of their patients’ hearts, whether they are healthy or not. Stress tests can also be performed for other reasons. A stress test can also be used, for example, to determine how much exercise is safe for one to perform. The stress test can be used to make a possible determination regarding any possibilities of an event such as a heart attack. Since the main goal of a stress test is to discover how healthy your heart is, a doctor won’t get it done without a reason. Simply because a stress test has been ordered in no way implies that the patient should assume the worst.
For example, the image must be sufficiently clear and a particular heart rate reached. If these important factors are satisfied, then this type of stress test can offer a reliable diagnosis in approximately 85% of coronary artery disease cases. Thus, there is no full guarantee of an accurate diagnosis and as you can see there are other contributing factors. There are a wide range of variables that can affect the accuracy of a diagnosis, including false positives.
As you can see, there are numerous uses for the cardiac stress test. Your cardiologist is the person who is best trained to determine what may be needed in any particular situation. It is also of the utmost importance to be conscious that all tests have limitations and this also refers to the cardiac stress test. For example, plenty depends on achieving the best heart rate. Stress tests with pictures rely on the quality of the pictures. There are also certain natural conditions and situations that can interfere with image quality, as well.
I wrote this article about Stress Test because it’s health related and while looking at a career in the med assisting arena, I authored a report about medical assistant schools you’ll find quite interesting.
