Premature MicroRNA-1 Expression Causes Hypoplasia of the Cardiac Ventricular Conduction System. [PDF]

, 2019
Mammalian cardiac Purkinje fibers (PFs) are specified from ventricular trabecular myocardium during mid-gestation and undergo limited proliferation before assuming their final form.

Transcriptomic Profiling of the Developing Cardiac Conduction System at Single-Cell Resolution.

Circulation Research, 2019
RATIONALE The cardiac conduction system (CCS) consists of distinct components including the sinoatrial node (SAN), atrioventricular node (AVN), His bundle, bundle branches (BB) and Purkinje fibers (PF).

Cardiac conduction system- A detailed study in 46 cases of sudden death

Journal of Pathology of Nepal, 2015
Background: Atherosclerotic coronary artery disease is the modern pandemic and is said to be responsible for a major chunk of sudden cardiac deaths. However, in few cases; especially among the young, conduction system abnormalities were found to be the ...

Deep Spatio-temporal Sparse Decomposition for Trend Prediction and Anomaly Detection in Cardiac Electrical Conduction [PDF]

arXiv, 2021
Electrical conduction among cardiac tissue is commonly modeled with partial differential equations, i.e., reaction-diffusion equation, where the reaction term describes cellular stimulation and diffusion term describes electrical propagation. Detecting and identifying of cardiac cells that produce abnormal electrical impulses in such nonlinear dynamic ...

New Insights into the Development and Morphogenesis of the Cardiac Purkinje Fiber Network: Linking Architecture and Function

Journal of Cardiovascular Development and Disease, 2021
The rapid propagation of electrical activity through the ventricular conduction system (VCS) controls spatiotemporal contraction of the ventricles. Cardiac conduction defects or arrhythmias in humans are often associated with mutations in key cardiac ...

A Case Report of Successful Physiological Pacing in a Patient With Lamin A/C Cardiomyopathy [PDF]

, 2022
BACKGROUND: Lamin A/C (LMNA) mutations account for 5-8% of familial dilated cardiomyopathies, and can manifest with conduction abnormalities and ventricular arrhythmias in 78% of patients. Therefore, when suspected, it is important to implant the correct

A comparison of Algebraic Multigrid Bidomain solvers on hybrid CPU-GPU architectures [PDF]

arXiv, 2023
The numerical simulation of cardiac electrophysiology is a highly challenging problem in scientific computing. The Bidomain system is the most complete mathematical model of cardiac bioelectrical activity. It consists of an elliptic and a parabolic partial differential equation (PDE), of reaction-diffusion type, describing the spread of electrical ...

Cardiac conduction system anomalies and sudden cardiac death: insights from murine models

Frontiers in Physiology, 2012
The cardiac conduction system (CCS) is a series of specialized tissues in the heart responsible for the initiation and co-ordination of the heartbeat. Alterations in the CCS, especially the His-Purkinje system, have been identified as an important player
