A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.
The Bruce exercise test involved walking on a treadmill while the heart was monitored by an electrocardiograph with various electrodes attached to the body. Breathing volumes and respiratory gas exchange were also monitored before, during and after exercise. Because the treadmill speed and inclination could be adjusted, this physical activity ...
Angina index is zero if no pain occurs during the exercise, one if the pain is limited to the exercise period but the patient can continue the exercise (typical angina), and two if a pain is a reason to stop the exercise test. [2] [3] Duke treadmill scores typically range from –25 (highest risk) to +15 (lowest risk).
Sonographer doing an echocardiogram of a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient's clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient's care.

Cardiac stress testing is used to determine to assess cardiac function and to disclose evidence of exertion-related cardiac hypoxia. Radionuclide testing using thallium or technetium can be used to demonstrate areas of perfusion abnormalities. With a maximal stress test the level of exercise is increased until the person's heart rate will not ...
Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP). It will be a direct indication of the energy demand of the heart and thus a good measure of the energy consumption of the heart.
A cardiac stress test, puts stress on the heart through exercise. A series of exercises to measure the tolerance for stress on the heart will be carried out. This test uses an EKG to detect the electrical impulses of the heart during physical exertion. [29] A treadmill or exercise bike will be used.
Echocardiogram: This test uses sound waves to produce a video image of the heart. With this test, the four chambers of the heart can be evaluated. Stress test: A stress test, also called an exercise stress test, provides information about how well the heart works during physical activity. It usually involves walking on a treadmill or riding a ...
