The Cardiac Conducting System of the Fowl*
Anatomia, Histologia, Embryologia, 1979AbstractTwenty‐four hearts of Brown Leghorn ranging in age from newly hatched to adult were investigated histologically to elucidate the topographical disposition of the entire cardiac conducting system. Through this study, the bird's heart was found to have the same specialized conducting system as that of mammals. Moreover, in addition to this system,

The anatomy of the cardiac conduction system
Clinical Anatomy, 2008AbstractAll the myocytes within the heart have the capacity to conduct the cardiac impulse. A population of myocytes is specialized so as to generate the cardiac impulse and then to conduct it from the atrial to the ventricular chambers. This population has become known as the conduction system.

Anatomy and Pathology of the Cardiac Conduction System
Cardiology Clinics, 2021The cardiac conduction system is formed of histologically and electrophysiologically distinct specialized tissues uniquely located in the human heart. Understanding the anatomy and pathology of the cardiac conduction system is imperative to an interventional electrophysiologist to perform safe ablation and device therapy for the management of cardiac ...

Sarcoidosis of the cardiac conducting system
American Heart Journal, 1979In a consecutive series of 2.950 routine autopsies two of 13 cases with sarcoidosis had cardiac involvement, one of which showed extensive granulomatous lesions in the sinus node. It is suggested that sudden death in this 52-year-old woman was caused by cardiac sarcoid involvement, possibly by leading to sinus arrest with cardiac standstill.

Pathology of the Cardiac Conduction System in Hemochromatosis
New England Journal of Medicine, 1964HEMOCHROMATOSIS is a disease of excessive iron storage leading to fibrosis and other tissue damage in many organs of the body. It has long been known that one of the organs frequently involved is the heart and that heart block and atrial arrhythmias are common manifestations of cardiac.

Computer simulation of the cardiac conduction system
Computers and Biomedical Research, 1983A discrete computer model simulating the operation of the cardiac impulse transmission apparatus and the electropotential changes of the heart musculature has been developed on a NORD-100 minicomputer. The model is written in NORD-FORTRAN and allows description of practically all basic pathologies of the transmission apparatus. A simulated ECG curve is

Development of the Cardiac Conduction System
The electrical impulses that coordinate the sequential, rhythmic contractions of the atria and ventricles are initiated and tightly regulated by the specialized tissues of the cardiac conduction system. In the mature heart, these impulses are generated by the pacemaker cardiomyocytes of the sinoatrial node, propagated through the atria to the ...Lieve E, van der Maarel +1 more

Mucormycete Infiltration in the Cardiac Conduction System
Canadian Journal of Cardiology, 2018A 74-year-old woman who took immunosuppression therapy died from a complete atrioventricular block and its complications. Autopsy findings suggested that mucormycosis of the cardiac conduction system had caused her complete atrioventricular block. This case demonstrates that infectious causes, including fungal infections like mucormycosis, can produce ...

Induction and patterning of the cardiac conduction system
The International Journal of Developmental Biology, 2002The cardiac conduction system (CCS) is the component of the heart that initiates and maintains a rhythmic heartbeat. As the embryonic heart forms, the CCS must continue to develop and mature in a coordinated manner to ensure that proper pace making potential and distribution of action potential is maintained at all stages.

Transcriptional regulation of the cardiac conduction system
Nature Reviews Cardiology, 2018The rate and rhythm of heart muscle contractions are coordinated by the cardiac conduction system (CCS), a generic term for a collection of different specialized muscular tissues within the heart. The CCS components initiate the electrical impulse at the sinoatrial node, propagate it from atria to ventricles via the atrioventricular node and bundle ...
