Abstract:
Objective To correctly analyze the positive results of electrocardiogram treadmill exercise test (TET) and improve the level of diagnosis of CHD Methods Two hundred and fifty eight patients with chest pain underwent TET and CAG; the case history and different clinical parameters were collected (1) Clinical data of the true positive group and the pseudo positive group were compared and underwent a statistic analysis (2) Clinical data of the female positive group were compared and underwent a statistic analysis Results The number of females in the pseudo positive group was larger than in the true positive group;The number of patients with typical chest pain, hyperlipidemic history, history of smoking, family history of CHD was smaller than in the true positive group;In the pseudo positive group,the changes of ST segment were mainly in Ⅱ, Ⅲ and aVF The number of extent of changes of more than 0 2 mV and with angina induced during exertion in pseudo positive group was smaller than in true positive group In females, under 60 years, the number of ST segment changes of resting ECG and left ventricular hypertrophy was larger in pseudo positive group than in true positive group The difference was significant Conclusion The factors including sex, typical chest pain,risk factors of CHD, the location and extent of ECG changes and angina induced following exertion should be combined to analyze the positive results of TET
