后壁心肌梗塞的诊断仍是复杂和困难的。传统认为其诊断基于 QRS 环向前移位,在右胸前导联产生宽大的 R 波,R/S>1;下壁导联出现 Q 波也是诊断所需的条件。但最初报告这些标准时,并无病理或血管造影的依据。后壁除极最晚,出现的异常在 QRS环的终末部份,故可被传导阻滞、左室肥厚等许多因素所掩盖。再者,在12个标准导联中;无后壁导联以供判断后壁异常之用。因此,作者回颐性地研究了由双平面左室造影和冠脉造影所估定的回旋支病变与后壁梗塞的病例。
Diagnosis of posterior myocardial infarction is still complex and difficult. The traditional diagnosis of QRS ring based on the forward shift in the right chest lead to produce a large R wave, R / S> 1; Q wave inferior leads is also required for diagnosis. However, when these criteria were first reported, there was no evidence of pathology or angiography. Posterior wall depolarization of the latest, the occurrence of abnormalities in the terminal part of the QRS ring, it can be blocked by conduction, left ventricular hypertrophy and many other factors covered. Again, in 12 standard leads; no posterior leads are available for judging the posterior wall abnormalities. Therefore, the authors studied the bipolar left ventricular diastolic angiography and biopsy assessed by circumflex artery lesions and posterior wall infarction cases.
