Hey first know wats stroke vol... SV = blood pumped by heart with each beat..
Pulse press= SBP-DBP
Syst BP depends on SV
Diastolic BP depends on TPR
For eg if SBP changes from 120 to 140 but ur DBP is 80 so PP= 140-80= 60
So if TPR is constant, greater SV means greater SBP so pulse pressure increases
I hope dis helps
