... Heart If we take average figures for the human left heart as follows : Q R = 60 c.c. , - 100 mm . Hg pressure in aorta = 0.1 × 13.6 grams ( 1 c.c. of Hg weighs 13.6 gm . ) , the expression QR may be evaluated as 60 X 0.1 m . x 13.6 81.6 ...

... Heart Lovatt Evans has shown that if the pressure in the right ventricle be assumed to be one - sixth that of the left , a close approximation to the total work of the heart can be obtained from the expression : where E - C - V W = 7QR ...
