Imaging ventricular fibrillation [PDF]

open access: yesJournal of Electrocardiology, 2007
Ventricular fibrillation (VF) had been traditionally considered as a highly disorganized process of random electrical activity emanating from multiple, short-lived, reentrant electrical waves. It is the incessant breakup of wave fronts and the creation of new daughter waves (wavebreaks) that perpetuate VF. Other studies described VF as a process with a

Impact of atrial fibrillation on the cardiovascular system through a lumped-parameter approach [PDF]

open access: yes, 2014
Atrial fibrillation (AF) is the most common arrhythmia affecting millions of people in the Western countries and, due to the widespread impact on the population and its medical relevance, is largely investigated in both clinical and bioengineering ...

A study of early afterdepolarizations in a model for human ventricular tissue [PDF]

open access: yes, 2014
Sudden cardiac death is often caused by cardiac arrhythmias. Recently, special attention has been given to a certain arrhythmogenic condition, the long-QT syndrome, which occurs as a result of genetic mutations or drug toxicity. The underlying mechanisms

Long QT syndrome provoked by induction of general anesthesia -A case report- [PDF]

open access: yesKorean Journal of Anesthesiology, 2010
Long QT syndrome (LQTS) is an arrhythmogenic cardiovascular disorder resulting from mutations in cardiac ion channels. LQTS is characterized by prolonged ventricular repolarization and frequently manifests itself as QT interval prolongation on the ...

The year in cardiology: arrhythmias and pacing. [PDF]

open access: yes, 2020
During this last year, there has been much progress with regard to anticoagulant and ablation therapy for atrial fibrillation (AF). Apart from recently issued European Society of Cardiology Guidelines for the management of patients with supraventricular ...

A novel approach for the diagnosis of ventricular tachycardia based on phase space reconstruction of ECG [PDF]

open access: yesInternational Journal of Cardiology, Volume 172, Issue 1, March 2014, Pages e31-e33, 2014
Ventricular arrhythmias comprise a group of disorders which manifest clinically in a variety of ways from ventricular premature beats (VPB) and no sustained ventricular tachycardia (in healthy subjects) to sudden cardiac death due to ventricular tachyarrhythmia in patients with and/or without structural heart disease.

Ventricular fibrillation and defibrillation [PDF]

open access: yesArchives of Disease in Childhood, 2007
Cardiac arrest in children is not often due to a disturbance in rhythm that is amenable to electrical defibrillation, contrary to the situation in adults. When a shockable rhythm is present, defibrillation using an external electric shock applied at an early stage after pre-oxygenation and chest compressions is of proven efficacy. Success at conversion

Higher ventricular rate during atrial fibrillation relates to increased cerebral hypoperfusions and hypertensive events [PDF]

open access: yesScientific Reports, 9: 3779, 2019, 2019
Atrial fibrillation (AF) is associated with cognitive impairment/dementia, independently of clinical cerebrovascular events (stroke/TIA). One of the plausible mechanisms is the occurrence of AF-induced transient critical hemodynamic events; however, it is presently unknown, if ventricular response rate during AF may impact on cerebral hemodynamics.

Vulnerability to ventricular fibrillation [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 1998
One of the factors that favors the development of ventricular fibrillation is an increase in the dispersion of refractoriness. Experiments will be described in which an increase in dispersion in the recovery of excitability was determined during brief episodes of enhanced sympathetic nerve activity, known to increase the risk of fibrillation.

Filament behavior in a computational model of ventricular fibrillation in the canine heart [PDF]

open access: yes, 2004
The aim of this paper was to quantify the behavior of filaments in a computational model of re-entrant ventricular fibrillation. We simulated cardiac activation in an anisotropic monodomain with excitation described by the Fenton-Karma model with Beeler ...
