Morphological Substrates for Atrial Arrhythmogenesis in a Heart With Atrioventricular Septal Defect

Frontiers in Physiology, 2018
Due to advances in corrective surgery, congenital heart disease has an ever growing patient population. Atrial arrhythmias are frequently observed pre- and post-surgical correction. Pharmaceutical antiarrhythmic therapy is not always effective, therefore

Artificial Cardiac Conduction System: Simulating Heart Function for Advanced Computational Problem Solving [PDF]

arXiv
This work proposes a novel bio-inspired metaheuristic called Artificial Cardiac Conduction System (ACCS) inspired by the human cardiac conduction system. The ACCS algorithm imitates the functional behaviour of the human heart that generates and sends signals to the heart muscle, initiating it to contract.

Identifying Cheating Anchor Nodes using Maximum Likelihood and Mahalanobis Distance [PDF]

arXiv, 2014
Malicious anchor nodes will constantly hinder genuine and appropriate localization. Discovering the malicious or vulnerable anchor node is an essential problem in Wireless Sensor Networks (WSNs). In wireless sensor networks, anchor nodes are the nodes that know its current location.

Gene Expression Profiling of the Forming Atrioventricular Node Using a Novel Tbx3-Based Node-Specific Transgenic Reporter

Circulation Research, 2009
The atrioventricular (AV) node is a recurrent source of potentially life-threatening arrhythmias. Nevertheless, limited data are available on its developmental control or molecular phenotype. We used a novel AV nodal myocardium–specific reporter mouse to

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 ...

Electrophysiology Study for Complex Supraventricular Tachycardia in Congenital Heart Disease Patients With Single‐Ventricle Physiology

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundSupraventricular tachycardia (SVT) is common in complex congenital heart disease (CCHD) patients with single‐ventricle physiology and may cause hemodynamic deterioration.

Computer Three-Dimensional Reconstruction of the Atrioventricular Node

Circulation Research, 2008
Because of its complexity, the atrioventricular node (AVN), remains 1 of the least understood regions of the heart. The aim of the study was to construct a detailed anatomic model of the AVN and relate it to AVN function.
