Exercise Stress Test Exercise Stress Test. A stress test, sometimes called a treadmill test or exercise test, helps a doctor find out how well your heart handles work. As your body works harder during the test, it requires more oxygen, so the heart must pump more blood. The test can show if the blood supply is reduced in the arteries that supply the heart.

Medical Dictionary A stress EKG is a type of EKG done during exercise. A resting EKG is always done before an exercise EKG test, and results of the resting EKG are compared to the results of the exercise EKG. A resting EKG may also show a heart problem that would make an exercise EKG unsafe. To learn more, see the topic Exercise Electrocardiogram.

Diagnosing heart disease Electrocardiogram (EKG) and stress test In an EKG, electrodes attached to the chest pick up electrical signals from the heart, which are then displayed as a line on a graph. It reveals how fast your heart is beating, whether it's beating in a regular pattern, and the size and thickness of the heart walls.

Stress Test or 3-D Scan? And the Best Heart Exam Is ... Half were randomly selected to get a computed tomographic angiography (CTA), which creates a 3-D image of the heart's arteries, allowing physicians to spot narrowing. The rest took stress tests — either an exercise electrocardiogram, a stress echocardiography or a nuclear stress test, which uses radioactive dye. Stress tests measure the heart's response to exertion, letting doctors see or hear any disease. The remarkable thing about the study is ...

What Happens During a Cardiac Stress Test? During the second phase of the test, pictures are taken of the heart. These pictures are compared with pictures taken prior to the exercise portion. How Long Does a Stress Test Take? While the exercise stress test itself usually takes around 10 or 15 minutes, part one of the test takes about 30 or 45 minutes total. Dr. Willke suggests blocking off most of your morning, because you will need to go in for follow-up photos about two hours later, for the second part of the test. How Does a Stress Test Work? Before the Test: Most doctors recommend fasting prior to a stress test. Usually we do them in the morning so we suggest fasting since midnight. It is easier and safer to do a stress test without a full belly, Dr. Willke explains.

stress test result, how long? One is the exercise nuclear stress test, where a Thallium (or like) dye is injected both before and after (actually, usuing during, at the end) of a regular ECG monitored exercise stress test on a treadmill. The other type is where a chemical is used to increase the heart rate instead of exercise.

What Happens During a Cardiac Stress Test? A stress test is an assessment done in two parts. In a very controlled situation, the heart is stressed using either exercise on a treadmill or a chemical injection, depending on the status of the individual getting the test. Heart rate, rhythm, and blood pressure are continuously monitored throughout the entire exam.

Cardiolite Stress Tests Doctors are able to get more accurate and complete information about how a patient's heart is functioning through a type of stress test called Cardiolite imaging. An exercise stress test with Cardiolite imaging is a diagnostic test that compares two heart scans. The first heart scan is a baseline scan done while a patient is at rest. An isotope, call Cardiolite, is injected by IV into the bloodstream and the resting heart scan is obtained.
