Physiology of the Cardiac Conduction SystemPhysiology of the Cardiac Conduction SystemThe diagnosis and management of cardiac arrhythmias has progressed rapidly as a science. Advances in the ability to diagnose and either suppress or eliminate arrhythmic substrates has taken an exponential trajectory. Wheth...
Furthermore, an extreme continuum of N isotopic variation is present in this xenolith: from very light N isotopic composition (delta(15)N(AIR) = -310 +/- 20 per thousand), similar to that inferred for the solar nebula, to the heaviest ratios measured in any solar system material (delta(...
Anatomy and Physiology of the Cardiac Conduction System The intrinsic conduction system of the heart is comprised of several specialized subpopulations of cells that either spontaneously generate electrical acti... PA Iaizzo,TG Laske 被引量: 4发表: 2010年 Neuregulin-1 promotes formation of the ...
We revealed their close relationship with sympathetic innervation during cardiac conduction system formation. Our study thus provides new insights into the development and heterogeneity of the mammalian cardiac conduction system by revealing a new cardiomyocyte population with potential catecholaminergic endocrine...
(1 percent of the cells) form the conduction system of the heart. Except for Purkinje cells, they are generally much smaller than the contractile cells and have few of the myofibrils or filaments needed for contraction. Their function is similar in many respects to neurons, although they are ...

6 The conduction tissues were implicated after clinicopathologic investigations that concentrated on the specialized myocardium and its neurons and ganglia. Some studies pointed to degenerative processes within and in the immediate environs of the conduction system. 3,4 展开 关键词:...
