Hyperchaotic behaviors, optimal control, and synchronization of a nonautonomous cardiac conduction system [PDF]

, 2021
In this paper, the hyperchaos analysis, optimal control, and synchronization of a nonautonomous cardiac conduction system are investigated. We mainly analyze, control, and synchronize the associated hyperchaotic behaviors using several approaches.

Neonatal Deletion of Hand1 and Hand2 within Murine Cardiac Conduction System Reveals a Novel Role for HAND2 in Rhythm Homeostasis

Journal of Cardiovascular Development and Disease, 2022
The cardiac conduction system, a network of specialized cells, is required for the functioning of the heart. The basic helix loop helix factors Hand1 and Hand2 are required for cardiac morphogenesis and have been implicated in cardiac conduction system ...

Regulation of Cardiac Conduction and Arrhythmias by Ankyrin/Spectrin-Based Macromolecular Complexes

Journal of Cardiovascular Development and Disease, 2021
The cardiac conduction system is an extended network of excitable tissue tasked with generation and propagation of electrical impulses to signal coordinated contraction of the heart.

Incidence of carditis and predictors of pacemaker implantation in patients hospitalized with Lyme disease

PLoS ONE, 2021
Background Lyme carditis, defined as direct infection of cardiac tissue by Borrelia bacteria, affects up to 10% of patients with Lyme disease. The most frequently reported clinical manifestation of Lyme carditis is cardiac conduction system disease.

In vivo visualization and molecular targeting of the cardiac conduction system

Journal of Clinical Investigation, 2022
Accidental injury to the cardiac conduction system (CCS), a network of specialized cells embedded within the heart and indistinguishable from the surrounding heart muscle tissue, is a major complication in cardiac surgeries. Here, we addressed this unmet

Cardiac Resynchronisation with Conduction System Pacing

Arrhythmia & Electrophysiology Review, 2023
To date, biventricular pacing (BiVP) has been the standard pacing modality for cardiac resynchronisation therapy. However, it is non-physiological, with the activation spreading between the left ventricular epicardium and right ventricular endocardium ...

Arrhythmias and Adaptations of the Cardiac Conduction System in Former National Football League Players [PDF]

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2019
Background Habitual high‐intensity endurance exercise is associated with increased atrial fibrillation (AF) risk and impaired cardiac conduction. It is unknown whether these observations extend to prior strength‐type sports exposure.

First in situ 3D visualization of the human cardiac conduction system and its transformation associated with heart contour and inclination

Scientific Reports, 2021
Current advanced imaging modalities with applied tracing and processing techniques provide excellent visualization of almost all human internal structures in situ; however, the actual 3D internal arrangement of the human cardiac conduction system (CCS ...

PRC1 Stabilizes Cardiac Contraction by Regulating Cardiac Sarcomere Assembly and Cardiac Conduction System Construction

International Journal of Molecular Sciences, 2021
Cardiac development is a complex process that is strictly controlled by various factors, including PcG protein complexes. Several studies have reported the critical role of PRC2 in cardiogenesis. However, little is known about the regulation mechanism of
