title: [Quantitative analysis of the structural organization of the human ventricular myocardium].
abstract: A special technique was worked out in order to study structural organization of the ventricular myocardium (90 human hearts without pathological signs) at macromicroscopical level. It is convenient to estimate spatial orientation of the cardiac contractile elements by the direction of fibrillar fasiculi at definite points. Quantitative characteristics on orientation of myocardial fibrillar fasciculi were obtained according to depth and extension of the cardiac wall in reference to the three-dimentional system of coordinates. Mathematical description of the structural organization of the ventricular myocardium was presented, the cardiac wall was considered as a thick envelope of a complex form. The structural organization was described by means of single vectors, tangents to the fibrillar fasiculi of the myocardium at the points of measurements.
