有些肺心病者心电图酷似心肌梗塞,极易误诊,临床多以急性或陈旧性前壁心肌梗塞入院,其心电图 V_1~V_3 或 V_1~V_4 导联呈QS 型,部分 S—T 段抬高等。笔者曾收治肺心病九例,均因入院时出现上述心电图波形而误诊为“心肌梗塞”,分析如下。一、临床资料一般情况:年龄50~70岁;女4例,男5例;均有慢性支气管炎(下称慢支)病史。均符合慢支、肺气肿、肺心病的临床表现,常规12导联心电图描记:V_1~V_3 导联呈 QS 型者7例,误诊为前间壁心肌梗塞;V_1~V_4 呈 QS 型2例,误诊为前壁心肌梗塞;2例 S—T 段抬高(超过正常限度)误诊为
Some pulmonary heart disease ECG resembles myocardial infarction, extremely easy to misdiagnosis, clinical and more to anterior or acute anterior myocardial infarction admitted, the ECG V_1 ~ V_3 or V_1 ~ V_4 lead was QS type, some S-T segment elevation. I had admitted to pulmonary heart disease nine cases, both because of admission ECG waveform was misdiagnosed as “myocardial infarction”, the analysis is as follows. First, the clinical data of the general situation: the age of 50 to 70 years old; 4 females, 5 males; have chronic bronchitis (hereinafter referred to as chronic bronchitis) history. All of them were consistent with the clinical manifestations of chronic bronchitis, emphysema and pulmonary heart disease. Conventional 12-lead electrocardiogram showed: 7 cases of QS type V_1 ~ V_3 lead were misdiagnosed as anterior myocardial infarction; 2 cases of V_1 ~ V_4 were QS type, Misdiagnosed as anterior myocardial infarction; 2 cases of S-T elevation (beyond the normal limit) misdiagnosed as
