The most important tool cardiologists use to diagnose heart diseases of any kind is the stress test. When a stress test is performed, a doctor will work with trained technicians to achieve the best results possible. There are different types of stress tests and each one has very specific requirements. Stress tests for cardiac disease have degrees of reliability that are influenced by testing and other conditions. Doctors need to examine the amount of stress the heart can handle before it is somehow altered or reacts to the stress. The exercise stress test, while best suited for a specific application, is the one that most people are familiar with.
Another type of stress test is the nuclear stress test which measures blood flow to the heart. This test is meant to measure the heart’s blood flow in exercise conditions as well as “at rest” conditions. The radioactive compounds used in the test to create the images are the reason for the “nuclear” name. So because there are two conditions of importance, what that means is imaging will need to be performed both while at rest and then during the time of exercise. There are a few differences such as the fact that the imaging aspect is performed immediately after exercising on a treadmill. The reason for this is so that physicians can record the movements of the heart while it is still in a state of stress.
The simplistic stress test is a system that is not as complex as other similar stress tests such as 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. That is done by the use of an EKG, or ECG, (electrocardiogram) monitor. The patient walks in a regular pace on the treadmill. Slowly, the pace of the treadmill is raised so that the stress on the heart goes up or the heart is in stress. During this time the doctor performs tests and is there just in case problems are on the horizon. Also, while this is going on, the blood pressure and rate of the patient is closely supervised.
It is extremely important that your heart receives normal and adequate blood supplies during heightened stressful situations and levels of physical activity. Stress tests might be ordered by your doctor for other reasons like trying to determine if a particular medicine will work for a particular form of heart disease. These kinds of medications are usually prescribed for angina and for getting other prevalent symptoms under control. Another very vital application is to find out how a specific medical procedure was formed such as bypass operations or the usage of stints. Many times people can develop irregular heartbeats as the years go by and the stress test is another way in which this can be diagnosed. Every kind of cardiac stress test has its benefits and a possible purpose. They serve to help doctors make the most accurate diagnosis possible. Keep in mind that there are optimum conditions involved with each test that will, or could potentially, have an effect on the accuracy of the results and diagnosis.
