由于心肌梗塞部位及范围不同,临床表现及并发症也不尽相同。依据心电图对心肌梗塞部位及范围的判定,虽各学者之间不完全一致,但大体上已有共同的趋向,经病理证实,都能反映得很准确。一般来说,广泛前壁及前间壁心肌梗塞来源于冠状动脉左前降枝病变,而下及后壁源于右支或回旋支病变。对于不同冠脉流域血流受阻而带来的心肌坏死及其所带来的异常病生状态,作相互比较的资料不多。文献上曾提到下后壁梗塞易于发生传导阻滞,又说前壁梗塞易于发生心力衰竭、心源性休克及其它异位心律紊乱等。究竟如何,也有待进一步验证。作者收集两个
Due to the different location and scope of myocardial infarction, clinical manifestations and complications are not the same. According to ECG determination of myocardial infarction site and scope, although not exactly the same among scholars, but generally have a common trend, confirmed by pathology, can reflect very accurately. In general, extensive anterior and anterior myocardial infarction is derived from left anterior descending coronary artery disease, while the inferior and posterior walls originate from right or malalignment. For different coronary blood flow caused by blockage of myocardial necrosis and its brought about the status of abnormal disease, compared with little information. Literature has mentioned the posterior wall infarction prone to conduction block, also said that anterior infarction prone to heart failure, cardiogenic shock and other ectopic heart rhythm disorders. What exactly is to be verified. The author collects two
