A sedative is a medicine that helps you feel relaxed. You are also given medicine (local anesthetic) to numb your throat. This helps you feel more comfortable during the procedure. An exercise stress test measures how your heart deals with the stress of physical activity.

A stress test is used to help diagnose and evaluate heart problems such as ischemic heart disease, heart valve disease, or heart failure. Your doctor may recommend this test if you have symptoms of a heart problem, such as shortness of breath, chest pain, dizziness, and a rapid or irregular heartbeat.Sep 27, 2019

After a baseline recording taken at rest, you begin walking on a treadmill at a slow pace (under 2 mph). Every few minutes, the speed and steepness of the treadmill increase, making you work harder. The goal is to exercise until you're too tired or out of breath.

You will be asked to walk on a treadmill for approximately 5 to 15 minutes. The test begins slowly and increases gradually in speed and incline every two to three minutes. During this time, your heart rate, blood pressure and EKG will be monitored.

• According to research from the American College of Cardiology, the sensitivity of a cardiac stress test without imaging is 68 percent, while its specificity is 77 percent. 7  (Sensitivity refers to a test's ability to render a correct positive diagnosis, while specificity refers to its ability to render a correct negative diagnosis).

• A health care provider will place several electrodes (small sensors that stick to the skin) on your arms,legs,and chest. ...
• The electrodes are attached by wires to an electrocardiogram (EKG) machine,which records your heart's electrical activity.
• You will then walk on a treadmill or ride a stationary bicycle,starting slowly.

• While stress testing can be performed in a variety of ways, the most commonly used and widely available stress testing modalities are exercise electrocardiography (ECG; non-imaging) and exercise or pharmacologic stress combined with imaging (stress echocardiography or stress radionuclide myocardial perfusion imaging [MPI]).

• This is a very reasonable option. However, if you had a stress test within the past two years and you remain asymptomatic, there is no need to repeat the test until it has been at least two years . This is where it is a bit tricky. It is reasonable to undergo stress testing if you fall in the high risk category.

Stress testing emphasizes on robustness, availability and error handling under a heavy load rather than on what is correct behavior under normal situations. Stress testing is defined as a type of software testing that verifies the stability and reliability of the system.

Transaction stress testing is performed on one or more transactions between two or more applications. It is carried out for fine-tuning and optimizing the system. Systematic stress testing is integrated testing which is used to perform test across multiple systems running on the same server.

The stress could be either walking very fast on an inclined treadmill or injection with drugs that stress the heart. The drugs typically used are dobutamine, persantine or adenosine. If a drug is used to stress the heart, it is referred to as a chemical stress test. The "Test" is how the function of the heart is measured.

The cost can range from $200 to $5,000—depending on the test. Why have a stress test? A stress test is performed to see if any part of the heart has decreased blood flow. It is typically ordered to determine if specific symptoms are related or not related to the heart.
