Idiopathic Ventricular Fibrillation
Herz Kardiovaskuläre Erkrankungen, 2007Idiopathic ventricular fibrillation (IVF) is responsible for a sizable part of sudden cardiac death (SCD). Furthermore, it has a high recurrence rate. Recent publications have shown that IVF is often caused by premature ventricular contractions (PVCs) arising from the right ventricular outflow tract (RVOT) or the Purkinje system.

Ventricular Fibrillation Frequency
Pacing and Clinical Electrophysiology, 2005Background: Ventricular‐fibrillation (VF) wave frequency is known to decrease with prolonged, untreated VF. VF wave frequency is used as an algorithm to identify VF in AEDs and ICDs; yet the nature of the frequency change is not appreciated. Methods: In this study, anesthetized pigs were used and VF was induced electrically.

Ventricular fibrillation masquerading as ventricular standstill
Critical Care Medicine, 1981After the induction of ventricular fibrillation (VF) in 29 animals, ECGs were serially recorded to determine whether a very low amplitude or a straight line ECG could occur in some leads while coarse fibrillatory waves were present in the other leads. Ventricular fibrillation was electrically induced via a transvenous catheter electrode advanced into ...

Initiation of ventricular fibrillation by atrial fibrillation
European Heart Journal, 1994We report the case of a patient who developed spontaneously a ventricular fibrillation during atrial fibrillation, 8 min after a perfusion of isoproterenol was stopped. Two mechanisms could explain the ventricular arrhythmia: silent ischaemia and a long-short cycle sequence just before ventricular fibrillation.

Primary Ventricular Fibrillation
New England Journal of Medicine, 1987Despite years of observation in coronary care units, there is still considerable uncertainty about the short-term and long-term prognostic implications of ventricular fibrillation in patients with ...

Idiopathic Ventricular Fibrillation
Journal of Cardiovascular Electrophysiology, 1997Idiopathic Ventricular Fibrillation. Idiopathic ventricular fibrillation is defined as cardiac arrest in the absence of structural heart disease and other identifiable causes of ventricular fibrillation. It occurs in 1% to 9% of survivors of out‐of‐hospital cardiac arrest. The mean age of these patients is 35 to 40 years, and 70% to 75% are male.

Spatiotemporal evolution of ventricular fibrillation
Nature, 1998Sudden cardiac death is the leading cause of death in the industrialized world, with the majority of such tragedies being due to ventricular fibrillation. Ventricular fibrillation is a frenzied and irregular disturbance of the heart rhythm that quickly renders the heart incapable of sustaining life.

An unusual cause of ventricular fibrillation
The Lancet, 2009In January, 2007, a 44-year-old previously healthy woman was admitted to the emergency department following resuscitation from ventricular fi brillation. Electrocardiogram showed ST depression, but coronary angio graphy showed no noteworthy stenosis. Transthoracic echo cardiography showed severe concentric left ventricular hypertrophy.

Ventricular tachyarrhythmias: Ventricular tachycardia and ventricular fibrillation
2018Ventricular tachyarrhythmias are abnormal patterns of electrical activity arising from the ventricular tissue (myocardium and conduction tissue). Ventricular tachycardia (VT) is an abnormal rapid heart rhythm originating from the ventricles. The rhythm may arise from the ventricular myocardium and/or from the distal conduction system.
