Heart Conduction System

Abstract The cardiac conduction system is a specialized collection of cells that generate and propagate action potentials throughout the heart in order to facilitate the synchronized contraction of myocardium. The system consists of the sinoatrial (SA) node, the atrioventricular (AV) node, and the His-Purkinje system. The SA node acts as

The Conduction System of the Heart

Archives of Internal Medicine, 1977
This fine monograph is the outgrowth of a structure-function workshop on cardiac conduction tissue held in the Netherlands in the spring of 1975. The three editors, all members of the Department of Cardiology and Clinical Physiology, Wilhelmina Gasthuis, Amsterdam, dedicated the volume to Dr Durrer.

Gangliosides of the bovine heart impulse conducting system

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1986
The ganglioside analysis of the heart impulse conducting system was carried out, comparing it with that of ordinary myocardium. The heart impulse conducting system contained about 3-times more gangliosides than ordinary myocardium and showed a distinctly different ganglioside composition.

The Pathology of the heart conduction system in congenital heart block

Journal of Clinical Forensic Medicine, 2006
The incidence of congenital complete heart block is estimated in 1 of 2500-20,000 births. Many cases are isolated (found in an otherwise normal heart) and the pathology of the heart conduction system is variable. We report a 51-year-old man with the diagnosis of complete heart block, with a permanent pacemaker.

Molecular and cellular diversity of heart conduction system myocytes

Trends in Cardiovascular Medicine, 1994
Conduction system myocytes are a subpopulation of cardiac myocytes that display unique electrophysiologic properties. Significant differences in cellular components of conduction myocytes have been demonstrated by the application of in situ procedures using both immunologic and molecular probes.

[Heart conduction system and accessory pathways].

Nihon rinsho. Japanese journal of clinical medicine, 1996
The morphology of atrioventricular (AV) junctions in the heart has been investigated using comparative anatomical analyses. For scanning electron microscopy, tissue blocks are treated with HCl to digest connective tissue elements. In fishes, amphibians and reptiles, there is a muscular system connecting the atrial muscle to the ventricular myocardium ...

Modeling and controlling the heart conductive system

2003 IEEE International Workshop on Workload Characterization (IEEE Cat. No.03EX775), 2004
A model of the cardiac tissue as a conductive excitable system with a pacemaker under external stimuli is proposed. At certain conditions this model is reduced to the standard circle map. It is analytically shown that 2-periodic perturbations of the constructed map lead to the stabilization of the prescribed orbits and thus, allow us to realize the ...

The Conduction System of the Heart

2014
The conduction system of the heart, which provides the heart its automatic rhythmic beat, consists of cardiac muscle cells and conducting fibers that initiate impulses and conduct them rapidly through the heart, initiate the normal cardiac cycle, and coordinate contractions of the cardiac chambers.

Neuropeptides and the conduction system of the heart

International Journal of Cardiology, 1992
Autonomic influences on the heart have been the subject of intense research for many decades but the dramatic expansion in cardiac electrophysiological studies in man has recently renewed clinical interest in autonomic control of the conduction system in health and disease.

[Disorders of the heart conduction system].

Vnitrni lekarstvi, 1991
Disorders of the genesis and conduction of impulses in different parts of the cardiac conduction system are the result of functional or morphological damage of parts of the conduction system. Pathological processes which affect the cardiac conduction system are practically always comprehensive and ensue from the character of the basic disease. Previous
