The end diastolic volume of a heart is 140 mL. Assume that it is a sphere. At end diastole, the intraventricular pressure is 7 mmIlg. The wall thickness at this time is 1.1 cm. At the end of isovolumetric contraction, the intraventricular pressure is 80 mmllg.
What is the wall tension at end diastole?
