Specialized impulse conduction pathway in the alligator heart

eLife, 2018
Mammals and birds have a specialized cardiac atrioventricular conduction system enabling rapid activation of both ventricles. This system may have evolved together with high heart rates to support their endothermic state (warm-bloodedness) and is ...

Dbh + catecholaminergic cardiomyocytes contribute to the structure and function of the cardiac conduction system in murine heart

Nature Communications, 2023
The heterogeneity of functional cardiomyocytes arises during heart development, which is essential to the complex and highly coordinated cardiac physiological function.

Heart conduction system: a neural crest derivative?

Brain Research, 1988
Using the anti-neurofilament monoclonal antibody iC8 we report here that muscle fibers of the conduction system of the adult and developing rabbit heart express a cytoskeletal protein antigenically and electrophoretically similar to the

Development of the conduction system of the heart

Pacing and Clinical Electrophysiology, 1997
The muscle cells forming the myocardium and the muscle cells forming the intestinal smooth muscle layers, are both derived from the visceral mesoderm. All cardiomyocytes display autorhythmicity, intercellular conduction via gap junctions, and contraction,

Complete Heart Block Lacking Functional Anatomical Impairment in the Conduction System

Pakistan Journal of Medicine and Dentistry
Introduction: Complete heart block also known as third-degree atrioventricular block (AV block) is a condition in which there is no conduction of the impulse produce in the sinoatrial node (SA node) in the atrium to the ventricle.1 Complete heart ...

Cardiac resynchronization therapy with conduction system pacing in a long-term heart transplant recipient: A case report

Indian Pacing and Electrophysiology Journal
We performed cardiac resynchronization therapy by means of conduction system pacing in a heart transplant patient suffering from heart failure with reduced ejection fraction and atrial fibrillation with conduction disturbance (bifascicular block and QRS >
