许多作者指出,慢性阻塞性肺疾病(COPD)的心电图变化,可能误诊为急性心肌梗塞(AMI),特别是左室前壁和后膈面的梗塞。容易发生混淆的原因是这两种病常见于同一病人,享有共同的危险因素(吸烟),均可发生室上性和室性心律失常,ORS波初始的向前向量减低或消失。用记录正切导联和普通12导联心电图的计算机分析法鉴别,在日常临床工作中不太实用。本文指出,从标准的12导联心电图检测所获得的特点可以迅速对COPD和AMI作出鉴别。【COPD的解剖和血液动力学改变】
Many authors note that ECG changes in patients with chronic obstructive pulmonary disease (COPD) may be misdiagnosed as acute myocardial infarction (AMI), particularly infarction of the left ventricular anterior and posterior diaphragmatic surfaces. The cause of confusion is that these two diseases are common in the same patient and share common risk factors (smoking). Both supraventricular and ventricular arrhythmias occur and the initial forward vectors of the ORS wave diminish or disappear. The use of tangential lead and ordinary 12-lead electrocardiographic computer analysis of identification, in clinical practice is not very practical. This article points out that the characteristics obtained from the standard 12-lead ECG test can quickly identify COPD and AMI. Anatomical and hemodynamic changes in COPD
