Evolution of the Sinus Venosus from Fish to Human

Journal of Cardiovascular Development and Disease, 2014
The sinus venosus, the cardiac chamber upstream of the (right) atrium, is a severely underinvestigated structure. Yet, its myocardium harbors the cardiac pacemaker in all vertebrates.

Conduction System Pacing for Cardiac Resynchronization Therapy

Journal of Cardiovascular Development and Disease, 2023
Cardiac resynchronization therapy (CRT) via biventricular pacing (BiVP-CRT) is considered a mainstay treatment for symptomatic heart failure patients with reduced ejection fraction and wide QRS. However, up to one-third of patients receiving BiVP-CRT are

Gradual differentiation and confinement of the cardiac conduction system as indicated by marker gene expression.

Biochimica et biophysica acta. Molecular cell research, 2020
The components of the cardiac conduction system, responsible for coordinated activation of the heart chambers, are well defined and their cells differ in gene expression profile and phenotype from those of the surrounding working myocardium.

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 ...

Intracardiac electrophysiological conduction parameters in adult dogs

Veterinary Quarterly, 2017
Background: Invasive electrophysiology study (EPS) is one of the most important adjunct tests for the evaluation of arrhythmias in human medicine. However, EPS is neither well known nor widely used in veterinary medicine.

Anomalous heat conduction and anomalous diffusion in nonlinear lattices, single walled nanotubes, and billiard gas channels

, 2004
We study anomalous heat conduction and anomalous diffusion in low dimensional systems ranging from nonlinear lattices, single walled carbon nanotubes, to billiard gas channels. We find that in all discussed systems, the anomalous heat conductivity can be

To reconnect or not reconnect distal Purkinje fibers, that is the question when modeling the Purkinje fiber network

Frontiers in Physiology
Background and aimsMultiple rule-based approaches exist to model the structure of the His-Purkinje system (HPS). While some approaches reconnect Purkinje fibers in the Purkinje fiber network, others do not.

Effects of Synaptic and Myelin Plasticity on Learning in a Network of Kuramoto Phase Oscillators [PDF]

, 2019
Models of learning typically focus on synaptic plasticity. However, learning is the result of both synaptic and myelin plasticity. Specifically, synaptic changes often co-occur and interact with myelin changes, leading to complex dynamic interactions ...

Conductivity of continuum percolating systems [PDF]

Physical Review E, 2001
We study the conductivity of a class of disordered continuum systems represented by the Swiss-cheese model, where the conducting medium is the space between randomly placed spherical holes, near the percolation threshold. This model can be mapped onto a bond percolation model where the conductance $ $ of randomly occupied bonds is drawn from a ...
