目的：以急性Q波心肌炎与急性心肌梗死（AMI）作对比，提供两者鉴别依据．方法：统计本院6年来急性Q波心肌炎患者18例，急性心肌梗死患者46例．动态观察心电图和心肌酶谱以及临床情况．结果：急性Q波心肌炎较急性心肌梗死发病较缓；肌酸磷酸激酶（CK）、谷草转氨酶（GOT）升高程度较急性心肌梗塞明显降低；急性心肌炎心电图上Q波3-7d后消失，T波治疗后2-3周恢复正常，ST段抬高但无对应导联ST段压低．结论：本研究表明，急性心肌炎有急性心肌梗死类型Q波和ST段抬高者预示病情严重．可依据临床情况心肌酶谱、心电图演变而与急性心肌梗死进行鉴别．
Objective: To compare the acute Q wave myocarditis and acute myocardial infarction (AMI), to provide the basis for the identification of the two. Methods: 18 cases of acute Q wave myocarditis and 46 cases of acute myocardial infarction in our hospital in 6 years were counted. Dynamic observation of ECG and myocardial enzymes and clinical situation. Results: The incidence of acute Q wave myocarditis was lower than that of acute myocardial infarction. The elevation of CK and GOT was significantly lower than that of acute myocardial infarction. The Q wave disappeared 3-7 days after acute myocarditis electrocardiogram. T Wave treatment returned to normal after 2-3 weeks, ST segment elevation but no corresponding lead ST segment depression. CONCLUSIONS: This study shows that acute myocardial infarction with acute myocardial infarction type Q wave and ST-segment elevation are predictive of serious illness. According to clinical conditions, myocardial enzymes, ECG changes and acute myocardial infarction were identified.
