Regulation of gap junction function; the role of nitric oxide. [PDF]

, 2013
Myocardial ischemia resulting from sudden occlusion of a coronary artery is one of the major causes in the appearance of severe, often life-threatening ventricular arrhythmias.

Identifying the evolutionary building blocks of the cardiac conduction system.

PLoS ONE, 2012
The endothermic state of mammals and birds requires high heart rates to accommodate the high rates of oxygen consumption. These high heart rates are driven by very similar conduction systems consisting of an atrioventricular node that slows the ...

Predictive factors of atrioventricular conduction disorders [PDF]

Romanian Medical Journal
Atrioventricular conduction disorders represent an alteration in the normal function of the heart’s electrical conduction system, a system that connects the atria and ventricles through the atrio-ventricular node and the His-Purkinje system. Consequently,

Early experience with permanent pacemaker implantation at a tertiary hospital in Nigeria

The Pan African Medical Journal, 2020
INTRODUCTION: Artificial pacemakers generate electrical impulses and regulate the heart´s conduction system. They are often used to treat individuals with bradycardia. Permanent pacemaker implantation is a lifesaving procedure especially in patients with

Incorporating Inductances in Tissue-Scale Models of Cardiac Electrophysiology [PDF]

, 2017
In standard models of cardiac electrophysiology, including the bidomain and monodomain models, local perturbations can propagate at infinite speed.

Nonlinear physics of electrical wave propagation in the heart: a review [PDF]

, 2016
The beating of the heart is a synchronized contraction of muscle cells (myocytes) that are triggered by a periodic sequence of electrical waves (action potentials) originating in the sino-atrial node and propagating over the atria and the ventricles ...

Global alternans instability and its effect on non-linear wave propagation : dynamical Wenckebach block and self terminating spiral waves [PDF]

, 2016
The main mechanism of formation of reentrant cardiac arrhythmias is via formation of waveblocks at heterogeneities of cardiac tissue. We report that heterogeneity and the area of waveblock can extend itself in space and can result formation of new ...

Impact of functional studies on exome sequence variant interpretation in early-onset cardiac conduction system diseases [PDF]

, 2020
Aims The genetic cause of cardiac conduction system disease (CCSD) has not been fully elucidated. Whole-exome sequencing (WES) can detect various genetic variants; however, the identification of pathogenic variants remains a challenge.

Recovery of complete left bundle branch block in dilated cardiomyopathy after optimal heart failure treatment: a case report [PDF]

Journal of Medicine and Life Science
Complete left bundle branch block (CLBBB) is a significant cardiac conduction abnormality often associated with dilated cardiomyopathy (DCM). This case report highlights the improvement in CLBBB and symptom relief through reverse cardiac remodeling in a ...
