孤立右室(RV)梗塞是一种少见的临床发现,据观察不足尸检者的2%。相反,左室(LV)下壁梗塞中20—45％有右室受累。左室梗塞常见为穿壁性,右室梗塞虽然可能很广泛,但多数为斑块性。 一、右室梗塞的诊断 1、临床特征 不足50％病例可见右心衰竭的临床征象,但广泛右心梗塞者,约75％可见右心衰竭的体征。
Isolated RV RV infarction is a rare clinical finding that is under-observed by less than 2% of autopsies. In contrast, 20-45% of infarcts in the left ventricular (LV) wall have right ventricular involvement. Common left ventricular infarction to wear wall, right ventricular infarction may be very broad, but most of the plaque. First, the diagnosis of right ventricular infarction 1, the clinical features of less than 50% of cases showed clinical signs of right heart failure, but a wide range of right heart infarction, about 75% visible signs of right heart failure.
