Fiber orientation across the left ventricular myocardial wall has been studied. Specimens
were obtained from 18 dog hearts rapidly fixed in situ in systole, in diastole, and in dilated …

During the early stages of ventricular systole, myocardial tension develops very rapidly,
ventricular pressure rises steeply to exceed arterial pressure, and momentum is then rapidly …
