Right ventricular outflow tract low‐voltage areas identify the site of origin of idiopathic ventricular arrhythmias: A high‐density mapping study

Cardiovascular Electrophysiology, 2019
Electronatomical mapping allows direct and accurate visualization of myocardial abnormalities. This study investigated whether high‐density endocardial bipolar voltage mapping of the right ventricular outflow tract (RVOT) during sinus rhythm may guide ...

Iatrogenic aortic regurgitation after radiofrequency ablation of idiopathic ventricular arrhythmias originating from the aortic valvular region.

Heart Rhythm, 2019
BACKGROUND Radiofrequency ablation at the aortic root has the potential risk of aortic regurgitation (AR). OBJECTIVE This study investigated the incidence and clinical features of iatrogenic AR after catheter ablation of idiopathic ventricular ...

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.

Lead I R‐wave amplitude to differentiate idiopathic ventricular arrhythmias with left bundle branch block right inferior axis originating from the left versus right ventricular outflow tract

Cardiovascular Electrophysiology, 2018
Differentiation of right versus left ventricular outflow tract (RVOT vs. LVOT) arrhythmia origin with left bundle branch block right inferior axis (LBRI) morphology is relevant to ablation planning and risk discussion.

Common and distinctive electrocardiographic characteristics and effective catheter ablation of idiopathic ventricular arrhythmias originating from different areas of ventricular septum adjacent to atrioventricular annulus

Cardiovascular Electrophysiology, 2018
To investigate electrocardiographic (ECG) characteristics and radiofrequency catheter ablation (RFCA) efficacy for premature ventricular complexes (PVCs) and idiopathic ventricular tachycardias (IVTs) originating from ventricular septum areas adjacent to

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.

[Clinico-immunological aspects of idiopathic ventricular arrhythmia].

Kardiologiia, 1992
The clinicoimmunological study revealed immunocompetence dysfunction in 28 patients with idiopathic ventricular arrhythmias resistant to ritmilen. After sodium nucleinate immunomodulation, ritmilen therapy proved to be beneficial in 46.6% of the patients.
