正后壁心肌梗塞,系指左心室后壁较高部位的心肌梗塞,在解剖上左室正后壁位于隔面之后方一小部分,在冠状沟之下,面对背脊。由于常规心电图胸导正极均集中在左室的前侧部,故当正后壁心肌梗塞时,在常规 V_(1-6)导联上不出现坏死型 Q 波,使诊断造
Posterior posterior wall myocardial infarction refers to a myocardial infarction in the upper part of the posterior wall of the left ventricle. A posterior part of the posterior wall of the left ventricle is anatomically located a small fraction behind the septa, facing the spine below the coronal groove. Because of the normal electrocardiogram chest positive leads are concentrated in the anterior chamber of the left ventricle, so when the posterior wall myocardial infarction, in the conventional V_ (1-6) lead does not appear necrotic Q wave, the diagnosis made
