左心室的后壁分后下壁、后侧壁和正后壁。正后壁位于下壁的后面,冠状沟下,面对背脊,故又称背壁(Dorsol wall)。国人约80—90％系冠状动脉右优势型,后壁的血供由右冠状动脉供应;而在冠状动脉左优势型者,其血液由左冠状动脉回旋支供应。后壁(特别是正后壁)心肌梗塞容易漏诊或误诊,兹将我们迂到的两例下壁合并正后壁(后下壁)心肌梗塞报道如下:
The posterior wall of the left ventricle is divided into posterior wall, posterior wall and posterior wall. Posterior wall is located in the back of the lower wall, Coronal, facing the back, it is also known as the Dorsol wall. About 80-90% of people in the Department of Coronary artery dominance, posterior wall of the blood supply from the right coronary artery supply; in the left coronary artery dominance, the blood supply from the left coronary artery. The posterior wall (especially posterior wall) myocardial infarction easily misdiagnosed or misdiagnosed, we will be detours of the two inferior posterior wall posterior wall (posterior inferior wall) myocardial infarction reported as follows:
