An essential part of diagnosing disease is through testing, and many people have had one kind of test or another. However, accurately finding heart problems and disease can be hard enough even with the high tech gadgets and equipment. One of these many tests is the cardiac stress test. This kind of test is frequently used by cardiologists to gain a clear picture of how well a person's heart reacts and responds to stress imposed within a controlled setting. The typical scenario involves an external stressor such as physical exercise; however stress can be induced through special drugs. The design is to reveal unusual or out of the ordinary blood flow to the heart. We will discuss several different types of cardiac stress tests in this article.
If there are current symptoms of heart disease, then a cardiac stress test might be give to look for blockage in the arteries of your cardiovascular system. Stress tests are very essential because many time there is no noticeable indication when a person is not under stress. Or, any other accompanying problem that is not detected because the heart is not under pressure. This is common knowledge because just like other things, problems do not arise until more pressure is present on the current demands.
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. The patient then has to walk at a ordinary speed on the treadmill. Gradually, the pace of the treadmill is increased so the demand on the heart is increased, or the heart is stressed. All this time, a doctor is present as well as other health technicians, to perform the test and be present in the event of any immediate problems. Additionally, during the test, the patient's blood pressure and heart are also observed.
A nuclear stress test uses radioactive isotopes to produce an image of the functioning of the heart during a stressful situation. It is easier to find if there are any problems with the cardiovascular system if the heart is tested under stress. Obtaining images of the heart at rest is also critical for the doctor. Thus, isotopes are introduced intravenously to aid in the creation of these images. Every kind of cardiac stress test has pros and goal. They assist in helping doctors make the most accurate diagnosis available. Remember that there are certain circumstances with each test that might have an effect on how the results and diagnosis are in terms of accuracy.
