The self-maintaining nature of ventricular fibrillation : contribution of L-type Ca²+ channels and Na+/Ca²+ exchange to cardiomyocyte Ca²+ overload in ventricular fibrillation : surface fluorescence study in isolated perfused rat hearts [PDF]

, 2004
Approximately 40% of all deaths in Switzerland are due to cardiovascular diseases.1 An important part of these deaths happen because of life-threatening cardiac arrhythmias.

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 ...

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.

Why Ablation of Sites With Purkinje Activation Is Antiarrhythmic: The Interplay Between Fast Activation and Arrhythmogenesis

Frontiers in Physiology, 2021
Ablation of sites showing Purkinje activity is antiarrhythmic in some patients with idiopathic ventricular fibrillation (iVF). The mechanism for the therapeutic success of ablation is not fully understood.

Variants in the SCN5A Promoter Associated With Various Arrhythmia Phenotypes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
Background Mutations in the coding sequence of SCN5A, which encodes the cardiac Na+ channel α subunit, have been associated with inherited susceptibility to various arrhythmias.

J point elevation in high precordial leads associated with risk of ventricular fibrillation

Annals of Noninvasive Electrocardiology, 2021
Introduction The significance of high precordial electrocardiograms in idiopathic ventricular fibrillation (IVF) is unknown. Method This study included 50 consecutive patients (48 men; age, 42 ± 18 years) who had spontaneous ventricular fibrillation not ...

Early Repolarization, Fragmented QRS and Tpeak-Tend Interval as Electrocardiographic Markers in Patients with Idiopathic Ventricular Arrhythmias: a Brief Review

Journal of Cardiac Arrhythmias, 2020
Introduction: Idiopathic ventricular tachycardia and ventricular fibrillation, as causes of sudden cardiac death, are entities with mechanisms poorly studied and understood to date. The electrocardiogram (ECG) is a simple tool, but with great diagnostic

Inappropriate shocks from a subcutaneous implantable cardioverter-defibrillator due to oversensing during periods of rate-related bundle branch block

Journal of Arrhythmia, 2017
The subcutaneous implantable cardioverter-defibrillator (S-ICD) is a novel technology with proven efficacy in sudden cardiac death prevention; however, there is a lack of long-term safety data.
