WebbA decrease in inotropy shifts the Frank-Starling curve downward (point A to B in the figure). This causes the stroke volume (SV) to decrease and the left ventricular end-diastolic pressure (LVEDP) and volume to increase. The change in SV is the primary response, whereas the change in LVEDP is a secondary response to the change in SV.
