Purkinje Cardiomyocytes of the Adult Ventricular Conduction System Are Highly Diploid but Not Uniquely Regenerative

open access: yesJournal of Cardiovascular Development and Disease, 2023
Adult hearts are characterized by inefficient regeneration after injury, thus, the features that support or prevent cardiomyocyte (CM) proliferation are important to clarify.

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

open access: yesJournal 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 ...

Identification of heart rate-associated loci and their effects on cardiac conduction and rhythm disorders [PDF]

open access: yes, 2013
Elevated resting heart rate is associated with greater risk of cardiovascular disease and mortality. In a 2-stage meta-analysis of genome-wide association studies in up to 181,171 individuals, we identified 14 new loci associated with heart rate and ...

Identifying the evolutionary building blocks of the cardiac conduction system.

open access: yesPLoS 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 ...

Innovations and mechanisms in pacing therapy for heart failure [PDF]

open access: yes, 2022
Despite pharmacological advances, heart failure remains a major cause of mortality and morbidity. Pacing therapy for heart failure was achieved in the 1990s with the advent of biventricular pacing (BVP).

Gradual differentiation and confinement of the cardiac conduction system as indicated by marker gene expression

open access: yes, 2020
The components of the cardiac conduction system, responsible for coordinated activation of the heart chambers, are well defined and their cells differ in gene expression profile and phenotype from those of the surrounding working myocardium.

Histochemical study of the heart conduction system [PDF]

open access: yes, 1980
The distribution of acid phosphatase and succinic dehydrogenase in the specialized muscle fibers constructing the heart conduction system (sinoatrial node, atrioventricular node, atrioventricular bundle and Purkinje fibers) and the ordinary heart muscle ...

Differentiation of the Atrioventricular Conducting System of the Heart [PDF]

open access: yesCirculation, 1961
The structure and function of the atrioventricular conducting system of the heart, and its relationship to the myocardium, are examined from a developmental point of view. On the basis of information derived from electron micrographic, electrophysiologic, and developmental studies of heart tissue, it is concluded that: (1) The idea of the syncytial ...

Variant Intronic Enhancer Controls SCN10A-Short Expression and Heart Conduction

open access: yes, 2021
BACKGROUND: Genetic variants in SCN10A, encoding the neuronal voltage-gated sodium channel Na V1.8, are strongly associated with atrial fibrillation, Brugada syndrome, cardiac conduction velocities, and heart rate.

Conduction Disturbances Associated with TAVR

open access: yes, 2023
Despite the improvement in the incidence of periprocedural complications associated with transcatheter aortic valve replacement (TAVR), conduction disturbances remain the most frequent complication of TAVR procedures.
