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.
Angina index will be zero if no pain appears 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 limiting pain occurs which is a reason to stop the exercise test. [2] [3] Duke treadmill scores typically range from -25 (highest risk) to +15 (lowest risk ...
The modified Bruce Protocol is an alteration in the protocol so that the treadmill is initially horizontal rather than uphill, with the 1st few intervals increasing the treadmill slope only. [3] The Bruce treadmill test estimates maximum oxygen uptake using a formula and the performance of the subject on a treadmill as the workload is increased ...
Johns Hopkins cardiologists analyzed 58,000 heart stress tests to come up with an algorithm called the FIT Treadmill Score. The score factors in peak heart rate and metabolism. The score factors ...
Initial experiments involved a single-stage test, in which subjects walked for 10 minutes on the treadmill at a fixed workload. Bruce's first paper on treadmill exercise tests, published in 1949, analyzed minute-by-minute changes in the respiratory and circulatory function of normal adults and patients with heart or lung ailments.
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.
The Harvard step test, in scientific literature sometimes referred to as the Brouha Test, is a type of cardiac stress test for detecting and diagnosing cardiovascular disease. It is also a good measurement of fitness and a person's ability to recover after a strenuous exercise by checking the recovery rate.
