What Is A Stress Test And Why They Are Used
Stress tests conducted on the heart using low dosage radioactive chemicals are known as nuclear stress tests. The idea behind the test is get a clear representation of blood flow through the heart.
This type of test is performed by a doctor to determine whether or not the patient has adequate blood flow. If blood flow is lower than regular, this serves as an alarm that there is a restriction, either in the heart or other arteries. When a nuclear test is given, the patient can be either exercising or at rest. Since exercise causes stress to the body, the heart and the complete cardiovascular system, the test is referred to as a stress test.
Your heart must have the capability of performing if placed under excessive load. Ascertaining that your heart is healthy and normal is the main goal of a stress test, no matter the reason your doctor ordered it. The non-nuclear stress test, namely the one involving exercise, is still used extensively in the medical field. Both treadmills and stationary bikes can be used for these tests. In order to watch the heart's electrical activity during the test, leads are connected to the patient's chest. A completely normal and healthy heart will reflect in the ECG - electrocardiogram. Likewise, a less healthy heart will also be revealed in the ECG.
The general stress test is a procedure that is not as hard as other types of stress tests like the nuclear stress test. During a generic test like the treadmill or standing bicycle test, the heart of the patient has to be observed. That is done by the use of an EKG, or ECG, (electrocardiogram) monitor. The patient then has to walk at a ordinary speed 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 is does a tests and is there in case any emergencies arise. Also, while this is going on, the blood pressure and rate of the patient is closely supervised.
It is very essential that your heart is given the proper amount of blood flow during those moments of higher stress. Stress tests might be administered for other things like trying to decide if a specific medication is good for a certain heart condition. Such medications are often prescribed for angina and other symptom 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. Plenty of times people will get irregular heartbeats over the years, and stress tests are a way to continue monitoring these.
Diagnosing different heart problems is much easier with the help of the nuclear stress test. If you ever need to have one performed, you should ask your doctor as many questions as possible. The more you enquire, the more you will learn about your condition and situation.
