There are many types of exercise stress test. One such test measures your ability to contract the muscles in your chest when you are under tension. During the exercise stress test, a device will apply varying levels of pressure on different parts of your chest. During this test, your heart is monitored to determine the changes in ventricular function caused by stress.
Another type of cardiac stress test measures the response of your heart to chemical stimuli. The perfusion component of the test measures the rate of blood flow in the heart by using a ventricular catheter inserted into the blood vessel. High levels of carbon dioxide will cause vasoconstriction (clamping) of the arteries. The infrared spect camera located at the end of the catheter will then show your heart's response to the chemicals.
Some people will have a higher risk factors for heart attacks or other heart problems because of their genetic make up. Stress test can also determine the risk factors in individuals that are at high risk. These individuals include overweight men, women over 40, smokers, those who are obese, those with hypertension, and those who have high cholesterol or low levels of triglycerides. The results will show whether or not you have any of these risk factors, which may put your life or the lives of your loved ones at risk.
Depending on what stress test you undergo, your doctor will provide a report detailing the test. You will need to prepare yourself mentally, and you may need to take some time out of your schedule. You will also need to decide whether or not you want to wear any comfortable clothes during your stress tests. If you feel you do not have to worry about being uncomfortable, then you may need to skip some stress tests. Your doctor will let you know what comfortable clothes you should wear.
Your doctor will probably ask you to complete a physical activity questionnaire before having you undergo a stress test. This questionnaire will request information about your current health, your medical history, the types of medications you are currently taking, your current occupation, and your level of education. The questionnaire will gather data on the factors that are associated with your response to physical activity and your functional capacity. After you undergo a stress test, your doctor will review your questionnaire and data and provide you with a detailed report on your results.
The results from a stress test will give your doctor an idea of how you react to stress. The ECG is used for diagnosis in the emergency treatment setting because it can quickly measure how severe your arrhythmias are. If there is any abnormal rhythm, such as rapid or irregular heart rate, your doctor will order an ECG to confirm it. ECG can also be used if there is unusual sweating in the lower extremities, unexplained shortness of breath, or low blood pressure.
