Short-coupled ventricular fibrillation represents a distinct phenotype among latent causes of unexplained cardiac arrest: a report from the CASPER registry.

European Heart Journal, 2021
AIMS The term idiopathic ventricular fibrillation (IVF) describes survivors of unexplained cardiac arrest (UCA) without a specific diagnosis after clinical and genetic testing.

Catheter Ablation in End-Stage Heart Failure with Atrial Fibrillation.

New England Journal of Medicine, 2023
BACKGROUND The role of catheter ablation in patients with symptomatic atrial fibrillation and end-stage heart failure is unknown. METHODS We conducted a single-center, open-label trial in Germany that involved patients with symptomatic atrial ...

Idiopathic ventricular fibrillation

American Heart Journal, 1990
A review of the literature dealing with sudden death revealed 19 articles in which ostensibly healthy patients with documented VF unrelated to any known cardiac or noncardiac etiology are reported. Fifty-four patients fulfilling the criteria for idiopathic VF, including 14 patients investigated at our institution, are described.

Ventricular fibrillation threshold

American Journal of Physiology-Legacy Content, 1961
The use of single rectangular stimuli, applied directly to the heart surface, has been confirmed as a reliable method for measurement of the ventricular fibrillation threshold (VFT). The following factors which influence reproducibility were investigated: 1) spatial separation of bipolar electrodes, 2) interval between stimuli, and 3) anatomical ...

Idiopathic Ventricular Fibrillation

Herz Kardiovaskuläre Erkrankungen, 2007
Idiopathic 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, 2005
Background: 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 tachycardia and ventricular fibrillation

Expert Review of Cardiovascular Therapy, 2009
Ventricular tachycardia and ventricular fibrillation are the most important causes of sudden cardiac death (SCD), particularly in those with structural heart disease and reduced left ventricular function. It is important to distinguish ventricular tachycardia from supraventricular tachycardia.

Primary Ventricular Fibrillation

New England Journal of Medicine, 1987
Despite 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, 1997
Idiopathic 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.

Idiopathic Ventricular Fibrillation

2010
Ventricular fibrillation (VF) in the absence of structural heart disease is classified as ’idiopathic ventricular fibrillation’or ’primary electrical disease’. In those cases the arrhythmogenic substrate should in principle be looked for in the excitation and conduction properties of the heart.
