چکیده
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. The pathogenesis is unknown; psychosocial factors may play a role. Baseline clinical characteristics have not been found to identify the 20% to 30% of patients who will have recurrent cardiac arrest. At present, implantation of an automatic defibrillator is the treatment of choice. Two registries have been established to enhance our knowledge of this unusual catastrophic entity.

Prevalence of the Brugada sign in idiopathic ventricular fibrillation and healthy controls.
OBJECTIVE To determine the prevalence of the Brugada sign (right bundle branch block with ST elevation in V1-V3) in idiopathic ventricular fibrillation and in an age matched healthy population. DESIGN ECGs from 39 consecutive patients with idiopathic ventricular fibrillation and 592 healthy controls were reviewed. They were classified as definite, questionable, and no Brugada sign (according ...
متن کاملLetter by Casado-Arroyo et al regarding article, "Electrocardiographic characteristics and SCN5A mutations in idiopathic ventricular fibrillation associated with early repolarization".
BACKGROUND Recently, we and others reported that early repolarization (J wave) is associated with idiopathic ventricular fibrillation. However, its clinical and genetic characteristics are unclear. METHODS AND RESULTS This study included 50 patients (44 men; age, 45 ± 17 years) with idiopathic ventricular fibrillation associated with early repolarization, and 250 age- and sex-matched healthy ...
متن کاملFavourable outcome in idiopathic ventricular fibrillation with treatment aimed at prevention of high sympathetic tone and suppression of inducible arrhythmias.
OBJECTIVE In the absence of an obvious cause for cardiac arrest, patients with idiopathic ventricular fibrillation are difficult to manage. A subset of patients has inducible arrhythmias. In others sympathetic excitation plays a role in the onset of the cardiac arrest. This study evaluates a prospective stepped care approach in the management of idiopathic ventricular fibrillation, with therapy...
متن کاملCatheter ablation of a monofocal premature ventricular complex triggering idiopathic ventricular fibrillation.
A 62 year old man was admitted for evaluation of recurrent episodes of syncope. A surface ECG showed frequent repetitive premature ventricular complexes of right ventricular outflow tract origin. Ventricular fibrillation was inducible by programmed electrical stimulation but otherwise cardiac evaluation was unremarkable. A diagnosis of idiopathic ventricular fibrillation was made and an implant...
متن کاملDiagnosis and long-term follow-up of the Brugada syndrome in patients with idiopathic ventricular fibrillation.
AIMS Some patients with idiopathic ventricular fibrillation may suffer from the Brugada syndrome. The diagnostic criteria for the Brugada syndrome are uncertain and arbitrarily set. Therefore, we studied the prevalence of the Brugada syndrome using various diagnostic criteria and long-term follow-up in 37 idiopathic ventricular fibrillation patients. METHODS AND RESULTS Idiopathic ventricular...
متن کاملIdiopathic ventricular fibrillation triggered by two distinct foci.
Idiopathic ventricular fibrillation (VF) is often triggered by short coupled ventricular premature beats originating from the ventricular Purkinje system or from the myocardium of the right ventricular outflow tract. We present a case of electrical storm due to idiopathic VF triggered from two distinct arrhythmogenic foci within the right ventricle. Successful radiofrequency ablation of both fo...
