The Analysis of the Factors Influencing the Accuracy of Treadmill Electrocardiogram Test

Treadmill Electrocardiogram Test (TET) is one of the most popular methods in the evaluation and diagnosis of Coronary Heart Disease (CHD). But the accuracy of the result is influenced by many factors, which leads to the higher ratio of false positive and false negative in the diagnosis of CHD. The most popular false positive factors include the sex, clinical performance, foundation electrocardiogram, symptom in treadmill electrocardiogram test, effect of disease, influence of medicine, disturbance of electrolyte and so on. On the other hand, the low volume of exercise, light stenosis of coronary, neutralization of correspondiog stenosis, increased collateral circulation, nontypical diseased region, symptom of chest pain without ST segment depression and influence of medicine lead to false negative diagnosis.
