Recurrent cardiac events in patients with idiopathic ventricular fibrillation, excluding patients with the Brugada syndrome

BMC Medicine, 2005
Background The recurrence of cardiac events in patients with idiopathic ventricular fibrillation (VF) excluding patients with the Brugada syndrome is unclear since this entity remains present in previous studies. Methods Since 1992, 18 patients (72% male)

Results of catheter ablation in patients with idiopathic premature ventricular contractions depending on the use of fluoroscopy

Российский кардиологический журнал, 2020
Premature ventricular contractions (PVC) is a very common type of arrhythmia. Some patients require surgical treatment. The search for the safest methods of surgical treatment is an important research task.Aim.

Effective cardiac resynchronization therapy for an adolescent patient with dilated cardiomyopathy seven years after mitral valve replacement and septal anterior ventricular exclusion

Journal of Cardiothoracic Surgery, 2010
Cardiac resynchronization therapy (CRT) is a new treatment for refractory heart failure. However, most heart failure patients treated with CRT are middle-aged or old patients with idiopathic or ischemic dilated cardiomyopathy.

Contact-force monitoring increases accuracy of right ventricular voltage mapping avoiding “false scar” detection in patients with no evidence of structural heart disease

Indian Pacing and Electrophysiology Journal, 2020
Purpose: Electroanatomical mapping (EAM) could increase cardiac magnetic resonance imaging (CMR) sensitivity in detecting ventricular scar. Possible bias may be scar over-estimation due to inadequate tissue contact.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Malignant idiopathic ventricular fibrillation cured by radiofrequency ablation

, 2008
Idiopathic Ventricular Fibrillation is a rare cause of sudden cardiac death. It may be difficult to prospectively diagnose idiopathic ventricular fibrillation due to the episodic nature of the arrhythmias as well as the inability to induce the clinical ...

Machine Learning‐Based Classification of Right and Left Ventricular Outflow Tract Premature Ventricular Contractions

Annals of Noninvasive Electrocardiology, Volume 31, Issue 6, November 2026.
Machine‐learning analysis of ECG‐derived features and demographic variables enables accurate and interpretable differentiation between RVOT‐ and LVOT‐originating premature ventricular contractions. ABSTRACT Introduction Idiopathic premature ventricular contractions (PVCs) commonly originate from the right and left ventricular outflow tracts (RVOT and ...

10-year follow-up after radiofrequency ablation of idiopathic ventricular arrhythmias from right ventricular outflow tract

Indian Pacing and Electrophysiology Journal, 2016
Background: The aim of this study was to examine the effect of radiofrequency ablation (RFA) of ventricular arrhythmias from right ventricular outflow tract (RVOT) during long-term follow-up.

Night syncope: a case report

Clinical Case Reports, 2017
Key Clinical Message “Idiopathic” ventricular fibrillations are rare and are estimated between 5% and 10% of survivors of hospital cardiac arrest, for at least some of them have as origin, a trigger in the Purkinje fibers. Interventional therapy could be
