CaMKII-dependent regulation of cardiac Na(+) homeostasis. [PDF]

open access: yes, 2014
Na(+) homeostasis is a key regulator of cardiac excitation and contraction. The cardiac voltage-gated Na(+) channel, NaV1.5, critically controls cell excitability, and altered channel gating has been implicated in both inherited and acquired arrhythmias.

Transient 2:1 Atrioventricular Block with Peri-Conduction System Pacing After Leadless Pacemaker Implantation [PDF]

open access: yesTexas Heart Institute Journal
This report discusses a case of transient 2:1 atrioventricular block with conduction system pacing 4 hours after leadless right ventricular pacemaker implantation in a 19-year-old patient with a history of cardioinhibitory syncope and asystole cardiac ...

Anatomic-electrophysiological correlations concerning the pathways for atrioventricular conduction. [PDF]

open access: yes, 2001
The remarkable success of radiofrequency ablation in recent decades in curing atrioventricular nodal reentrant tachycardias has intensified efforts to provide a solid theoretical basis for understanding the mechanisms of atrioventricular transmission ...

HSPB7 prevents cardiac conduction system defect through maintaining intercalated disc integrity

open access: yesPLoS Genetics, 2017
HSPB7 is a member of the small heat-shock protein (HSPB) family and is expressed in the cardiomyocytes from cardiogenesis onwards. A dramatic increase in HSPB7 is detected in the heart and blood plasma immediately after myocardial infarction ...

Value of multi-detector computed tomography in delineation of the normal cardiac conduction system and related anatomic structures

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2016
The cardiac conduction system is responsible for rhythmic myocardial stimulation for physiologic contraction of the heart. Aim of the work: To assess the value of MDCT in outlining anatomic landmarks and variants of conductive system, therefore provides ...

Virtual cardiac monolayers for electrical wave propagation [PDF]

open access: yes, 2017
The complex structure of cardiac tissue is considered to be one of the main determinants of an arrhythmogenic substrate. This study is aimed at developing the first mathematical model to describe the formation of cardiac tissue, using a joint in silico ...

Impact of functional studies on exome sequence variant interpretation in early-onset cardiac conduction system diseases [PDF]

open access: yes, 2020
Aims The genetic cause of cardiac conduction system disease (CCSD) has not been fully elucidated. Whole-exome sequencing (WES) can detect various genetic variants; however, the identification of pathogenic variants remains a challenge.

Current Advance, Challenges and Future Perspectives of Conduction System Pacing

open access: yesReviews in Cardiovascular Medicine
Existing techniques for pacing the right ventricle and providing cardiac resynchronization therapy through biventricular pacing are not effective in restoring damage to the conduction system.

Sodium leak through K2P potassium channels and cardiac arrhythmia, an emerging theme. [PDF]

open access: yes, 2017
In this issue of EMBO Molecular Medicine, Decher et al (2017) identify a point mutation in the K2P2 (TREK‐1) potassium (K+) channel that changes function in just those ways expected to predispose to right ventricular outflow tract (RVOT) ventricular

Conduction defects and arrhythmias in mdx mice are not associated with a degeneration of the cardiac Purkinje network

open access: yesFrontiers in Physiology
Duchenne muscular dystrophy (DMD) is a severe X-chromosomal disease characterised by progressive muscle weakness and degeneration. Cardiac involvement is inevitable in DMD patients and ventricular arrhythmias are a high-risk factor for mortality in these
