An endogenous cholinergic system controls electrical conduction in the heart. [PDF]

Eur Heart J
Abstract Background and Aims The cholinergic system is distributed in the nervous system, mediating electrical conduction through acetylcholine (ACh). This study aims to identify whether the heart possesses an intact endogenous cholinergic system and to explore its electrophysiological functions and ...

Surgical and Electrical Anatomy of the Inter-Nodal and Intra-Atrial Conduction System in the Heart

Journal of Chest Surgery, 2022
An anatomical understanding of the atrial myocardium is crucial for surgeons and interventionists who treat atrial arrhythmias. We reviewed the anatomy of the inter-nodal and intra-atrial conduction systems. The anterior inter-nodal route (#1) arises from the sinus node and runs through the ventral wall of the atrial chambers. The major branch of route

Electrical Conduction System Remodeling in Streptozotocin-Induced Diabetes Mellitus Rat Heart [PDF]

Frontiers in Physiology, 2019
Cardiovascular complications are common in type 1 diabetes mellitus (TIDM) and there is an increased risk of arrhythmias as a result of dysfunction of the cardiac conduction system (CCS). We have previously shown that, in vivo, there is a decrease in the heart rate and prolongation of the QRS complex in streptozotocin-induced type 1 diabetic rats ...

Surgical Outcomes of Congenital Heart Disease in Down Syndrome: Tertiary Center Experience—Focus on the Electrical Conduction System [PDF]

Pediatric Cardiology, 2022
Abstract Purpose: To document outcomes of cardiac surgical repair in Down syndrome (DS) patients with specific focus on the associated electrical conduction morbidities, ultimately leading to a higher incidence of pacemaker implantation (PMI). Methods: A retrospective study conducted between 2011 to 2020.

Modelling the impulse distribution, delay and block in the electrical conduction system of the heart bundles

Perm Scientific Center Journal, 2018
In the article the excitatory irradiation in the electrical conduction system was numerically modeled. The overview of transmembrane potential of electrical conduction system was given. The Luo-Rudi model (2011) was chosen for the investigation. A finite element model of the electrical conduction system was built in which the latter was regarded as a ...

Conduction system pacing versus biventricular pacing in heart failure with reduced ejection fraction and electrical dyssynchrony

Frontiers in Cardiovascular Medicine
Biventricular pacing (BiVP) has been the cornerstone of cardiac resynchronization therapy (CRT) in the management of symptomatic heart failure patients with reduced ejection fraction (HFrEF) and electrical dyssynchrony despite guideline-directed medical therapy (GDMT).

High resolution 3-Dimensional imaging of the human cardiac conduction system from microanatomy to mathematical modeling [PDF]

, 2017
Cardiac arrhythmias and conduction disturbances are accompanied by structural remodelling of the specialised cardiomyocytes known collectively as the cardiac conduction system.

Modeling the Heart as a Communication System [PDF]

, 2014
Electrical communication between cardiomyocytes can be perturbed during arrhythmia, but these perturbations are not captured by conventional electrocardiographic metrics.

Electrical activation of the ventricular myocardium of the crocodile Crocodylus johnstoni: A combined microscopic and electrophysiological study [PDF]

, 1999
We mapped the sequence of ventricular depolarization in the crocodile Crocodylus johnstoni. We also attempted to find specialized conduction tissue within the ventricular myocardium.
