单纯性右室梗塞(RVI)很少见,尸检发现低于2％,而左室下壁梗塞20～45％可累积右室。左室梗塞(LVI)多为透壁性,RVI常为斑点状。 RVI的血液动力学改变 RVI可致室壁的收缩性丧失。动物试验显示,由于双心室系心肌螺旋形环绕而成,即使RV完全被烧灼,LV收缩产生的张力仍能传递到RV,推动RV的血液进入肺循环,维持正常的心输出量和压 Right ventricular infarction (RVI) is rare, less than 2% of autopsy findings, and 20-45% of infarcts in the left ventricle accumulate in the right ventricle. Left ventricular infarction (LVI) mostly transmural, RVI often spotted. RVI hemodynamic changes in RVI caused loss of contractility of the ventricular wall. Animal studies have shown that due to the biventricular myocardial spiral encircling, even if the RV is completely cauterized, the tension generated by LV contraction can still be transmitted to the RV, pushing the blood of the RV into the pulmonary circulation, maintaining normal cardiac output and pressure
