Radiofrequency Catheter Ablation of Idiopathic Right Ventricular Outflow Tract Arrhythmias [PDF]

Indian Pacing and Electrophysiology Journal, 2013
Idiopathic ventricular arrhythmias (VA) consist of various subtypes of VA that occur in the absence of clinically apparent structural heart disease. Affected patients account for approximately 10% of all patients referred for evaluation of ventricular ...

Electrocardiographic characteristics of idiopathic ventricular arrhythmias based on anatomy [PDF]

Annals of Noninvasive Electrocardiology, 2020
AbstractIdiopathic ventricular arrhythmia (IVA) is a term used to describe a spectrum of ventricular arrhythmia without structural heart disease (SHD). IVAs contain premature ventricular contractions (PVCs), nonsustained monomorphic ventricular tachycardia (VT), and sustained VT.

The V6R/V4R Index: A Novel ECG Parameter for Identifying Idiopathic Ventricular Arrhythmias Originating From the Aortic Cusp. [PDF]

J Cardiovasc Electrophysiol
The V6R/V4R amplitude index is a novel and practical electrocardiographic parameter for identifying idiopathic ventricular arrhythmias originating from the aortic cusp. A cutoff >0.55 accurately distinguishes cusp from adjacent non‐cusp origins within the left ventricular outflow tract, facilitating targeted mapping and procedural planning.

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

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

Late elimination of challenging idiopathic ventricular arrhythmias originating from left ventricular summit by anatomical ablation [PDF]

Indian Pacing and Electrophysiology Journal, 2019
Ablation of premature ventricular complexes (PVCs) originating from left ventricular outflow tract (LVOT)/left ventricular summit (LVS) is challenging with considerable rate of failure.

A Comprehensive Review of Left Ventricular Summit Ventricular Arrhythmias

Journal of Tehran University Heart Center, 2022
The catheter ablation of idiopathic ventricular arrhythmias is accepted as a first-line treatment as it successfully eliminates about 90.0% of such arrhythmias.

Moderator Band and Ventricular Tachycardia: Structural or Functional Substrate?

Journal of Cardiovascular Development and Disease, 2023
The moderator band (MB) is an intracavitary structure of the right ventricle composed of muscular fibers encompassing specialized Purkinje fibers, separated each other by collagen and adipose tissue.

Catheter Ablation of Idiopathic Ventricular Arrhythmias Originating from the Para-Hisian area - QRS Morphology Change and Late Effect of the Ablation: Case Series [PDF]

Folia Medica, 2020
Introduction: Radiofrequency catheter ablation of idiopathic ventricular arrhythmias originating in the para-Hisian region could be challenging because of a potential risk of iatrogenic atrioventricular block.
