10. STRESS TESTING A stress test is a medical test that indirectly reflects arterial blood flow to the heart during physical exercise. When compared to blood flow during rest, the test reflects imbalances of blood flow to the heart's left ventricular muscle tissue – the part of the heart that performs the greatest amount of work pumping blood
11. The first standardized cardiac stress test was developed in 1929 by Arthur Master, The patient either walks on a treadmill or is given IV medication that simulates exercise while connected to an electrocardiogram machine. The level of exercise is increased every 3-minute. The patient's symptoms and blood pressure response are repeatedly checked. When using ECG and blood pressure monitoring alone the test is variously called a cardiac stress test, exercise stress test, exercise treadmill test, exercise tolerance test, stress test or exercise ECG test.
