Atrial cellular electrophysiological changes in patients with ventricular dysfunction may predispose to AF [PDF]
, 2009 <b>Background:</b> Left ventricular systolic dysfunction (LVSD) is a risk factor for atrial fibrillation (AF), but the atrial cellular electrophysiological mechanisms in humans are unclear.

Case report: electrical storm during induced hypothermia in a patient with early repolarization
BMC Cardiovascular Disorders, 2017 Background Population based studies showed an association of early repolarization in the electrocardiogram (ECG) and a higher rate of sudden cardiac death presumably due to ventricular fibrillation.

The incidence and risk factors for new onset atrial fibrillation in the PROSPER study [PDF]
, 2011 Aims Atrial fibrillation/flutter (AF) is the most common arrhythmia in older people. It associates with reduced exercise capacity, increased risk of stroke, and mortality. We aimed to determine retrospectively whether pravastatin reduces the incidence of

Duration of heart failure and the risk of atrial fibrillation: different mechanisms at different times? [PDF]
, 2009 Chronic heart failure increases the risk of atrial fibrillation (AF), with the prevalence of AF paralleling the severity of heart failure.1 Factors that underlie this increased susceptibility to AF may include electrical, structural, and neurohumoral ...

Mechanisms of termination and prevention of atrial fibrillation by drug therapy [PDF]
, 2011 Atrial fibrillation (AF) is a disorder of the rhythm of electrical activation of the cardiac atria. It is the most common cardiac arrhythmia, has multiple aetiologies, and increases the risk of death from stroke.

A preliminary assessment of the effects of ATI-2042 in subjects with paroxysmal atrial fibrillation using implanted pacemaker methodology [PDF]
, 2009 Aims ATI-2042 (budiodarone) is a chemical analogue of amiodarone with a half life of 7 h. It is electrophysiologically similar to amiodarone, but may not have metabolic and interaction side effects.

New model of ventricular fibrillation [PDF]
Journal of Electrocardiology, 2005 The purpose of this study was to develop a more efficient and stable model of ventricular fibrillation (VF) in the isolated rabbit heart, because there is not a satisfactory model with this animal. We also observed the effects of increasing extracellular calcium in the stability and reversibility of the arrhythmia.

Ventricular Fibrillation [PDF]
Circulation: Arrhythmia and Electrophysiology, 2017 See Article by Panitchob et al > As to the fundamental mechanisms of fibrillation we have plenty of theories, but none is universally accepted… we may note in passing that they all center around two ideas … (a) that the impulses arise from centers or pacemakers, or (b) that the condition is caused by re-entry of impulses and the formation of circles ...
