Endocardial Fibroelastosis of Large Mammals
Normal hearts of a mouse, rat, man, sea lion, hippopotamus, elephant, and blue whale were shown to have different numbers of myocardial fibers, 10 7 to 10 13 , based on calculations involving their myocardial fiber diameters and nuclear density counts. These two parameters did not vary greatly in th...
