The atria and the ventricles of the heart contract rhythmically and sequentially to achieve efficient blood flow. This contraction pattern is orchestrated by the cardiac conduction system, comprising specialized cardiomyocytes that initiate and propagate the cardiac electrical impulse.

Scenario:A 59-year-old woman had brief episodes of rapid atrial fibrillation and bradycardia several months ago. It was not recurrent or sustained, so she was not treated with invasive or pharmacological interventions but followed up with occasional clinic visits.

Conductivity in disordered systems
Physical Review B, 1985By combining numerical results on wires of finite cross section with the coherent-potential approximation and the potential-well analogy, a formula for the conductivity of a three-dimensional disordered system is obtained which interpolates between the weak-scattering limit and the mobility edge.

Pacing of Specialized Conduction System
Cardiac Electrophysiology Clinics, 2021Right ventricular pacing for bradycardia remains the mainstay of pacing therapy. Chronic right ventricular pacing may lead to pacing-induced cardiomyopathy. We focus on the anatomy of the conduction system and the clinical feasibility of pacing the His bundle and/or left bundle conduction system.

Abstract Conduction system hamartoma is a benign hamartomatous lesion arising from Purkinje and Purkinje-like cells of the heart. We aimed to investigate the cases that we detected during postmortem histopathological examination. The histopathology reports of the cases autopsied between 2012 and 2022 were reviewed retrospectively.

Distal Atrioventricular Conduction System Function
Cardiology Clinics, 1986This article addresses electrophysiologic evaluation of the distal AV conduction system in patients with chronic bifascicular block. It was formerly thought that progression to complete AV block was a common cause of morbidity and even sudden death in this condition, and it was hoped that electrophysiologic evaluation, including measurement of the H-V ...

The Conduction System in Heterotaxy
World Journal for Pediatric and Congenital Heart Surgery, 2011Cardiac malformations associated with the syndrome of atriovisceral heterotaxy are among the most complex forms of congenital heart disease. Accordingly, the disposition of the specialized conduction tissue (the conduction system) is also variable and complex in these particular anomalies.

The hexactinellid sponge Rhabdocalyptus dawsoni is capable of arresting its exhalant water current in response to mechanical and electrical stimuli. The arrest is coordinated by a conduction system with a precise threshold of excitability and a chronaxie of 38 milliseconds.

In the normal heart, the electrical impulse arises from the sinus node, and it is transmitted from the atria to the ventricles only through the Tawarian atrioventricular (AV) conduction axis (i.e., AV node, His bundle, and bundle branches) and Purkinje fibers, after a slowdown at the AV node, which allows the atria to empty during ventricular diastole.
