Direct reprogramming of cardiomyocytes into cardiac Purkinje-like cells

open access: yesiScience, 2022
Summary: Currently, there are no treatments that ameliorate cardiac cell death, the underlying basis of cardiovascular disease. An unexplored cell type in cardiac regeneration is cardiac Purkinje cells; specialized cells from the cardiac conduction ...

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

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

A 21st century view of the anatomy of the cardiac conduction system

open access: yesTranslational Research in Anatomy, 2022
Introduction: Since the discovery of the major components of the cardiac conduction system (CCS) by the early 20th century we have seen many technological advancements that have allowed immense insight into the CCS tissues. In this review we will discuss

Modeling the Heart as a Communication System [PDF]

open access: yes, 2014
Electrical communication between cardiomyocytes can be perturbed during arrhythmia, but these perturbations are not captured by conventional electrocardiographic metrics.

Bidirectional ventricular tachycardia in cardiac sarcoidosis. [PDF]

open access: yes, 2016
A 73-year-old man with history of pulmonary sarcoidosis was found to have runs of non-sustained bidirectional ventricular tachycardia (BVT) with two different QRS morphologies on a Holter monitor.

Development and Function of the Cardiac Conduction System in Health and Disease

open access: yesJournal of Cardiovascular Development and Disease, 2017
The generation and propagation of the cardiac impulse is the central function of the cardiac conduction system (CCS). Impulse initiation occurs in nodal tissues that have high levels of automaticity, but slow conduction properties.

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

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

Genetic and physiologic dissection of the vertebrate cardiac conduction system.

open access: yesPLoS Biology, 2008
Vertebrate hearts depend on highly specialized cardiomyocytes that form the cardiac conduction system (CCS) to coordinate chamber contraction and drive blood efficiently and unidirectionally throughout the organism.

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

open access: yes, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.
