急性心肌梗死心电图的不典型改变

The ECG atypical changes in acute myocardial infarction

目的探讨急性心肌梗死（AMI）的不典型心电图表现及发生率。方法对352例AMI患者进行心电图检查、心电监护、24h动态心电图及心肌酶学检测、冠状动脉造影。结果AMI患者不典型心电图表现为微小q波伴不同程度ST段抬高、延迟出现q／Q波、仅ST—T改变，发生率为14．5％。结论AMI心电图不典型表现有多种改变。

Objective To investigate the ECG atypical changes in acute myocardial infarction（AMI）. Methods 352 patients with AMI were selected sequentially and examined by electrocardiogram （ECG） , Hoher of 24h, myocardial enzymes testing and coronary angiography, and electrocardio-monitoring was performed at the same time. Data were analyzed by statistics. Results The incidence of ECG atypical changes in patients with AMI was 14. 5%. The ECG atypical changes including Q wavelet with the elevation value of ST segment, the delays of Q wave and the only changes of ST-T. Conclusion The above several kind of ECG performane are present in atypical AMI.
