A cardiac stress test is a medical test performed to evaluate arterial
blood flow to (and indirectly the amount of oxygen that will reach) the
myocardium (heart muscle) during physical exercise, compared to blood
flow while at rest. As an exercise test, the results can also reflect
overall physical fitness. These tests do not assess emotional stress or
other connotations of the term.
Stress test abnormalities (i.e., "positive" results) are an indication
of imbalances of relative blood flow to the left ventricular muscle
tissue. This is important because the left ventricle of the heart
performs the greatest amount of work involved in pumping blood around
the body. Stress testing does not detect blood flow imbalances within
the other three heart chambers.
