Mode of Onset of Malignant Ventricular Arrhythmias in Idiopathic Ventricular Fibrillation

Journal of Cardiovascular Electrophysiology, 1997
Mode of Onset of Idiopathic VF. Introduction: The mode of onset of malignant ventricular arrhythmias (ventricular tachycardia [VT] or ventricular fibrillation [VF] has been well described in patients with organic heart disease and in patients with the long QT syndromes. Less is known about the mode of onset of VF in patients with out‐of‐hospital VF who

Ablation for idiopathic ventricular arrhythmia – with and without arrhythmia-induced cardiomyopathy

Scandinavian Cardiovascular Journal, 2014
We conducted a study to assess the procedural success and long-term freedom from arrhythmia in patients treated with radiofrequency ablation (RFA) for idiopathic ventricular arrhythmia (VA) with and without arrhythmia-induced cardiomyopathy (AIC).We identified 131 patients treated with RFA for idiopathic VA in our institution; 16 of whom had AIC.

Electrocardiographic landmarks of idiopathic ventricular arrhythmia origins

Heart, 2019
Idiopathic ventricular arrhythmias occur in the absence of underlying structural heart disease and less commonly in the presence of coexistent, but mechanistically unrelated, myocardial scar. These arrhythmias originate from several anatomical sites in both ventricles, with a predilection in outflow tract structures.

Significance of ventricular arrhythmias in idiopathic dilated cardiomyopathy

The American Journal of Cardiology, 1984
The incidence and prognostic significance of ventricular arrhythmias identified by 24-hour ambulatory electrocardiography (Holter) was prospectively assessed in 74 patients with idiopathic dilated cardiomyopathy (IDC). The criteria for diagnosis of IDC were based on clinical and cardiac catheterization findings.

Idiopathic ventricular arrhythmia in a young man: a case report

Emergency Medicine Journal, 2009
Ventricular ectopics can potentially lead to ventricular fibrillation (VF). A case of idiopathic VF that began as ventricular bigeminy is presented. A 30-year-old man lost consciousness transiently while driving but made a complete recovery soon after. He was pale and sweaty at the onset of the event.

Significance and reproducibility of exercise-related idiopathic ventricular arrhythmias

European Heart Journal, 1980
Fifty-five patients with a severe idiopathic ventricular arrhythmia were subjected to a follow-up study three to seven years after the discovery of the arrhythmia. During this time only one sudden cardiac death had occurred. Special attention was paid to comparing the clinical significance and reproducibility of arrhythmias either aggravated or ...

Electrocardiographic Difference between Ventricular Arrhythmias from the Right Ventricular Outflow Tract and Idiopathic Right Ventricular Arrhythmias

Pacing and Clinical Electrophysiology, 2014
BackgroundVentricular arrhythmias (VA) arising from arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) and idiopathic right ventricular outflow tract ventricular arrhythmias (RVOT‐VA) share the pattern of left bundle branch block (LBBB)/inferior axis.

Electrocardiographic Algorithms to Localize the Origins of Idiopathic Ventricular Arrhythmias

Pacing and Clinical Electrophysiology, 2012
The first step forapproaching the catheter ablation of VAs is todetermine the likely site of the VA origin byevaluating the surface electrocardiograms (ECGs).This process will guide one to the designfor an ablation strategy and can improve thesuccess rate and safety of the procedure.
