逻辑顺序？

Pump failure is usually caused by right ventricular dysfunction exacerbated by increased pulmonary vascular resistance secondary to pulmonary contusion, aspiration of gastric contents, or ARDS. An initial right ventricular free wall dilation may be followed by leftward ventricular septal shift, which alters the geometry and compliance of the left ventricle, increasing left ventricular filling pressure and decreasing cardiac output. This condition should by no means be a signal to decrease fluid loading. On the contrary, volume replacement should continue with concomitant use of inotropes and pulmonary vasodilators.

老师，leftward ventricular septal shift是跟着right ventricular free wall dilation后面发生的吧?这段话的逻辑是这样的吗？肺血管阻力上升----泵衰竭----右室游离壁扩张----室间隔左移----心排血量下降----补液、强心、扩肺血管？xiexie
