Sinus Node and Atrial Arrhythmias [PDF]

open access: yesCirculation, 2016
Although sinus node dysfunction (SND) and atrial arrhythmias frequently coexist and interact, the putative mechanism linking the 2 remain unclear. Although SND is accompanied by atrial myocardial structural changes in the right atrium, atrial fibrillation (AF) is a disease of variable interactions between left atrial triggers and substrate most ...

A study on stability analysis of atrial repolarization variability using ARX model in sinus rhythm and atrial tachycardia ECGs [PDF]

open access: yes, 2016
© 2016 Elsevier Ireland Ltd Background The interaction between the PTa and PP interval dynamics from the surface ECG is seldom explained. Mathematical modeling of these intervals is of interest in finding the relationship between the heart rate and ...

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

open access: yes, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Wandering Bundles With Sinus Arrhythmia

open access: yesJACC: Case Reports, 2023
A 3-year-old boy with congenital ventricular septal defect underwent a closure procedure. Telemetry after the procedure reveals sinus arrhythmia with varying types of bundle branch blocks. Inverse decremental conduction in left posterior fascicle, related to preceding RP interval during sinus arrhythmia, underlies changes between right and left bundle ...

Reduced vagal tone in women with the FMR1 premutation is associated with FMR1 mRNA but not depression or anxiety

open access: yesJournal of Neurodevelopmental Disorders, 2017
Background Autonomic dysfunction is implicated in a range of psychological conditions, including depression and anxiety. The fragile X mental retardation-1 (FMR1) premutation is a common genetic mutation that affects ~1:150 women and is associated with ...

Electrocardiographic patch devices and contemporary wireless cardiac monitoring. [PDF]

open access: yes, 2015
Cardiac electrophysiologic derangements often coexist with disorders of the circulatory system. Capturing and diagnosing arrhythmias and conduction system disease may lead to a change in diagnosis, clinical management and patient outcomes.

Contact force sensing in ablation of ventricular arrhythmias using a 56-hole open-irrigation catheter: a propensity-matched analysis. [PDF]

open access: yes, 2021
PURPOSE: The effect of adding contact force (CF) sensing to 56-hole tip irrigation in ventricular arrhythmia (VA) ablation has not been previously studied.

Cardioversion in Infantile Atrial Flutter

open access: yesPakistan Armed Forces Medical Journal, 2022
Atrial flutter (AFL) is a rare arrhythmia in neonatal and infantile period. Potentially, AFL might lead to severe morbidity and even a fatal outcome.
