Physiology of Myocardial Contraction
2002The principal function of the heart is to propel oxygenated blood to the peripheral tissues to meet their metabolic demands. The systemic arterial and venous systems provide the conduits. The interaction of the left ventricle (LV) with the arterial and venous systems is therefore integral to the satisfactory performance of this vital function.

A Note on the Influence of Asynchronous Activation on Myocardial Contraction
Acta Physiologica Scandinavica, 1972AbstractPairs of rabbit papillary muscles were mounted in series to make it possible to study the effects of asynchronous activation on myocardial contraction. The two muscles were connected together via platinum loops hooked to a lever (displacement transducer), the other end of each muscle being fixed to a force transducer.

Myocardial contraction band necrosis in stranded cetaceans
Journal of Comparative Pathology, 1998The term contraction band necrosis describes focal hypercontraction and lysis of small groups of myocardial cells. Contraction band necrosis of the myocardium was identified in 100% of 52 whales and dolphins (cetaceans) stranded along the western coast of the Gulf of Mexico between April 1991 and November 1996.

[Reversible dysfunction of myocardial contraction].
Vnitrni lekarstvi, 1999It has been known for more than 20 years that in some patients after revascularization partial or complete improvement of previous left ventricular dysfunction occurs. The condition for this improvement is viable myocardium, i.e. contractile reserve. Chronic reversible contractile dysfunction, also called hibernating myocardium heart muscle is along ...

[Cardiac myosins and myocardial contraction].
Giornale italiano di cardiologia, 1987The contractile properties of cardiac muscle cells are determined by the molecular composition of the contractile apparatus and in particular by the structure of myosin. Three isoforms of myosin heavy chains have been recently identified in the mammalian heart: alpha and beta myosin heavy chains, present in atrial and ventricular myocardium, and nodal ...

The Intrinsic Control of Myocardial Contraction — Ionic Factors
New England Journal of Medicine, 1971THE heart is an organ that is notable for its ability to adapt very rapidly to changes in demand even in the absence of extrinsic neural or humoral stimuli.
