• If the ventricle is operating<br />
on the steep part of the<br />
curve increasing preload<br />
must induce an increase in<br />
SV (preload responsiveness).<br />
• If the ventricle is operating<br />
on the flat part of the curve<br />
increasing preload will not<br />
induce any significant<br />
increase in stroke volume<br />
(preload unresponsiveness).
