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

[Surgery of the heart conduction system].

Kardiologiia, 1979
Problems concerned with surgery of the heart conduction system are discussed. Two operations performed directly on the heart conduction system are analysed: operation for dividing the bundle of His or Keith's node with subsequent implantation of electrocardiostimulators in ventricular tachycardia unresponse to drugs and operation for dividing the walls

[Morphology of the heart conduction system].

Ceskoslovenska patologie, 1980
Using his own experience and literary research, the author gives an outline of the morphology of the conduction systems of normal children's and adult hearts, including its blood supply.
