心电图运动试验对疑诊为冠心病患者是一种有诊断价值的无创伤性试验,可以评价临床不典型胸痛之原因及早期检出冠心病。本文根据239例患者踏车运动试验(ET)结果,初步探讨其临床应用价值。资料与方法一、对象本组239例中,男170例,女69例。年龄25～72岁。其中211例有不典型胸痛、胸憋,休息时,心电图(ECG)正常或大致正常;28例为心律失常,尚难确诊病因,包括房性、交界性及室性早搏,阵发性室上性心动过速,阵发性房颤,左前分支阻滞,Ⅰ°房室传导阻滞或完全性右束支传导阻滞 ECG exercise test for patients with suspected coronary heart disease is a diagnostic noninvasive test that can assess the causes of atypical chest pain and early detection of coronary heart disease. This article based on 239 patients treadmill exercise test (ET) results, preliminary study of its clinical value. Materials and Methods First, the object 239 cases in this group, male 170 cases, female 69 cases. Age 25 ~ 72 years old. Among them, 211 cases had atypical chest pain, chest and back resting, and electrocardiogram (ECG) were normal or almost normal; 28 cases were arrhythmia, it was difficult to confirm the etiology, including atrial, borderline and premature ventricular contractions, paroxysmal supraventricular Tachycardia, paroxysmal atrial fibrillation, left anterior branch block, Ⅰ ° atrioventricular block, or complete right bundle branch block
