whaht is the effect of end diastolic volume Perload on the

ejection fraction

cardiac contractility and

strock volume

  #2

i think sroke volume increase and and contractility decrease and i don't know about ejection fraction.
well i m wrong let me know.
thanx.

  #3

increased end diastolic volume will increase the contractily leading to increase in stroke volume as well as ejection fraction

u were just about there mani
In increased cardiac contractility there is proportionate increase of both strock volume and end diastolic volum

ef=sv/edv , so if both increased so the ratio remains constant

  #5

ok i get it

I JUST WANT TO ADD THIS

When u talk about athletics and B1 stimulant drugs the EF will change, ie increase not because I was wrong but because u have to draw different curve in which the relationship between strock volume and EDV changes
