:aargh4: I am studying Valley and there is a table on page 151 of the manual from 2007. It is asking about with increased preload the EDV increase, the ESV has no change, the SV increase, MAP increases,SVR increases, PCWP increases and HR decreases, but what happens to the left ventricular chamber size? I believe it either decreases or has no change. Others say that the LV chamber size increases. Can someone help me please? I am trying to master these concepts.
