The intrinsic conduction system of the heart is comprised of several specialized subpopulations of cells that either spontaneously generate electrical activity (pacemaker cells) or preferentially conduct this activity throughout the chambers in a coordinated fashion.

Archives of Internal Medicine, 1975
The recording of electrograms directly from the surface of the heart in situ has been a part of many standard experimental procedures for decades. However, it is only recently that electrograms have been recorded specifically from the atrioventricular conduction system of the heart in situ.

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

Conduction system disease in cardiac amyloidosis
Trends in Cardiovascular MedicineCardiac amyloidosis (CA) has diverse and deleterious effects on the conductive system. Atrial fibrillation is by far the most common electrophysiological manifestation of CA and is associated with more mortality, morbidity, and hospitalizations. While AF increases the risk of thrombosis regardless of the CHA2DS2-VASc score, the risk of thromboembolism ...

Symptomatic Conduction System Disease in Cardiac Amyloidosis
The American Journal of Cardiology, 1997Symptomatic conduction system disease in cardiac amyloidosis and its management has been reported infrequently. We report our experience of patients with amyloidosis having symptomatic conduction system disease requiring permanent pacemaker implantation.

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.

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 ...

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 ...

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.
