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

Annals of Noninvasive Electrocardiology, 2020
Idiopathic 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),

Incidence of Idiopathic Ventricular Arrhythmias: A Population-Based Study. [PDF]

Circ Arrhythm Electrophysiol, 2017
Background— Ventricular tachycardia and premature ventricular complexes (PVCs) most frequently occur in the context of structural heart disease. However, the burden of idiopathic ventricular arrhythmias (IVA) in the general population is unknown. Methods

Ablation of idiopathic ventricular arrhythmias. [PDF]

Neth Heart J, 2018
Idiopathic ventricular arrhythmias (IVA) is a term commonly used to describe premature ventricular complexes (PVCs) or ventricular tachycardias (VT) in the absence of structural heart disease. Most IVA (approximately 70%) arise from the right ventricular

Idiopathic Annular Ventricular Arrhythmias

Arrhythmia & Electrophysiology Review
Idiopathic arrhythmias originating from the mitral and tricuspid annuli are commonly encountered in clinical practice. This review focuses on distinguishing features of ventricular arrhythmias arising from these structures and the importance of ...

Cardiac Magnetic Resonance to Detect the Underlying Substrate in Patients with Frequent Idiopathic Ventricular Arrhythmias. [PDF]

Diagnostics (Basel), 2021
Background: A routine diagnostic work-up does not identify structural abnormalities in a substantial proportion of patients with idiopathic ventricular arrhythmias (VAs). We investigated the added value of cardiac magnetic resonance (CMR) imaging in this

Predictors of Left Ventricular Scar Using Cardiac Magnetic Resonance in Athletes With Apparently Idiopathic Ventricular Arrhythmias. [PDF]

J Am Heart Assoc, 2021
Background In athletes with ventricular arrhythmias (VA) and otherwise unremarkable clinical findings, cardiac magnetic resonance (CMR) may reveal concealed pathological substrates.

Idiopathic ventricular arrhythmias: Relevance to the anatomy, diagnosis and treatment. [PDF]

Journal of Cardiology, 2016
Idiopathic ventricular arrhythmias (VAs) are ventricular tachycardias (VTs) or premature ventricular contractions (PVCs) whose mechanisms are not related to myocardial scar.

Radiofrequency Catheter Ablation of Idiopathic Right Ventricular Outflow Tract Arrhythmias

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 ...
